The Making of an American Truck | Exceptional Engineering | Free Documentary

[Music] [Music] [Music] a massive hood a huge engine a spacious cab and a roomy sleeper the classic American truck in the late 1970s Swedish manufacturer Volvo began producing trucks overseas specifically for the North American market a truck rolls off the assembly line every 10 minutes a scale of manufacturing that cause for vast quantities of material anything that holds up the assembly line threatens to delay production and must be avoided at all cost the bump manipulator has broke down all them Magnus cannot get it fixed we'll start installing bunks behind customers have a choice of more than 500 different colors for the cab and the chassis the truck is roadworthy just one day after rolls off the production line once it's passed all the tests on the in-house test track more new trucks in one day than most drivers will drive their entire life trucks are the most popular means of transporting goods in the US 70% of cargo in North America is transported by Road a figure that continues to rise more than 500,000 big rigs with that distinctive huge hood that left the Volvo factory since the late 1970s [Music] double in Virginia home to the largest Volvo truck manufacturing facility in the world and one of the largest in the u.s. 3,500 employees build trucks here for the North American market [Music] the flagship vehicle is the VNL the long-haul truck comes in several models the smallest model has a relatively modest cab the biggest is the sleeper the VNL 860 which has space for two bunks it has a width of over six and a half feet the high roof model has an inside height of eight and a half feet there's a choice of 11 liter 13 litre and 15 liter engines their power output ranges from 375 to 565 horsepower depending on the application the maximum speed is nearly 90 miles per hour the skeleton of every model are these steel girders building the chassis takes a few hours the workers start by securing the girders with over 400 bolts more than 60 different bolts are used in the manufacturing process and each has a specific function the biggest is 13 centimeters long the basic structures are assembled at a rate of one every two minutes these are transported to the next workstation on a dolly along the way to each station in the plant the next station is where the trucks air suspension is installed three compressors power what's called the air ride chassis the components that will be assembled over the next few hours have to be delivered at exactly the right time to exactly the right place there's limited space in the factory so many of the parts are only made available at the precise point that they're needed several hundred axles are delivered to the production line every day [Music] ensuring that assemblage run smoothly is a massive logistical undertaking keeping the conveyor belt moving and preventing production from stalling means each component has to be in exactly the right place at exactly the right time up until this point the chassis has been assembled upside down for the sake of convenience now weighing approximately two and a half tons the truck is turned around [Music] the next step is the installation of what's called the fifth wheel that makes it sound superfluous but in fact it's a vitally important component this is what we call a fifth wheel it's not actually a wheel but what it is it's a locking mechanism for the pin on the trailer so the truck can pull the trailer once in use these trucks will be transporting tons of cargo every day the fifth wheel is attached to the chassis with 32 extra strong screws [Music] the entire chassis is then painted with a clear lacquer making it durable and resistant ten minutes later the frame is dry [Music] meanwhile the cab is being built in another part of the factory first the side parts are preassembled then they're transported to a robot that welds everything together they're putting those two pieces together so by the time it comes off the other end of this line that sub-assembly is ready to be transported over to the main line where they're going to begin the process of putting the bulkhead in the floor pan together and then put the side panels in place a bit like a house of cards the side parts are now placed on the floor pan one on the right side and one on the left [Music] a worker fixes the sheets with a spot welder [Music] welding robots then takeover to ensure they're 100% secure welding over 100 spots in the space of four minutes [Music] once the roof is in place the cabin is complete this process is fully automated [Music] next the cab is coated to prevent rust before the painting process can begin the workers manually seal all corners and edges of the cab with silicone to prevent moisture from seeping in [Music] then robots apply primer all the calves get the same gray primer regardless what color will be applied later the cabs are then lined up at the factory paint kitchen customers can pick out a color from a palette of over 500 options [Music] there are over 100 different shades of white alone there is very little difference an actual pigment of the color it's really what the customer wants so some customers have a very specific color that identifies their brand identity that they mark it so that's the color that we go with and that they pick if you look at these two colors here there are almost identical but they are two different paint codes for two different customers the paint doesn't come in a can but directly from the paint kitchen in hoses several hundred meters long every four minutes around seven liters of paint are pumped to the robots not a drop is wasted now push the paint to the robot and then from the robot we flush it out through solve it comes back up these lines and the solvent pushes everything all the paint back to the kitchen and we will reuse a whatever paint we can reuse and we also reuse a solvent the kitchen is where the paint is mixed because the whole room is full of highly flammable paints and thinners it is specially protected against fire and explosion safety is the top priority so electrical appliances are banned in the paint kitchen including cell phones only explosion-proof phones are permitted once the paint has been delivered to the robots it's atomized into a spray by a rotating nozzle the paint particles are also given a positive electrostatic charge and the cab a negative electrostatic charge is breaking up the paint particles and is spinning the paint particles onto the product itself by doing so you get better or transfer efficiency you can use less paint it takes six to seven minutes to paint the cab depending on the assemblage once dry the color tone is inspected with a spectral measuring device if the device finds an error all responsible persons are automatically informed [Music] it's red it sends a red flag up to our quality engineers an email text bench is sent to their phone they'll immediately come down here and check and actually take the manual chip and manually chip it against it to make sure it's okay Greensboro North Carolina home to the company's Technical Center and top-secret development department visitors aren't allowed here and cameras are strictly forbidden Jason Spencer's product strategy director for North America at Volvo Trucks Driver Safety was one of his primary considerations in the planning of the newest model after running numerous crash tests he and his colleagues came up with a design that ensures maximum protection for the truckers in the event of an accidents [Music] you're the first on the scene for example when you hit something you're right over top of it in a truck like this you have a lot of mass in front of you to absorb energy before the driver is impacted but it takes more than save cabins and excellent crash test results to sell a truck customers want more they want comfort the integrated king-size bed with adjustable headrest is a major selling points when I'm parked on an incline a surface that's not level you know when you're sleeping in your feeder above your head you wake up with my headache well if they're able to incline their bunks likely they don't have to worry about where they're parking their truck things like this or you know really we we realize this is a home run nowadays Volvo is one of the largest truck manufacturers in the US the VNL 860 is a top seller it has a high roof and an interior height of eight and a half feet the sleeper is over six and a half feet wide and six and a half feet long standard equipment includes a microwave refrigerator and TV you can see how large I am and how much space I have in this bed there's so much we even have our sleeper control panels it can control the air conditioning back here I can turn the lights on and off my temperature I also have a refrigerator over here and we actually have another bed up here I'll bring it on down and we even have a ladder that we can bring down to get into that bag we have lights up here as well we kind of charge reports up here we have our airline style shades so it's easy to block out the Sun if you want to sleep you got a television you have a microwave for when you're resting if you want to cook food on the go the truck is designed to accommodate two drivers because truck routes in the US are so long a vehicle is often shared and both truckers need their own space the front of the truck is very different from a passenger car if I stand up you'll notice the chair will will address it's going to to drop back down see the auto adjust now when I sit back down give it a minute starts to adjust in it based on my my weight kind of gives me the height at things I'm going to want instead of gear sticks more than 90% of vehicles are equipped with a 12 speed automatic transmission complete with performance and economy buttons [Applause] [Music] but American truckers most popular accessory is probably the giant drink holder up to three one and a half liter cups can be stowed here enough coffee to make sure no trucker nods off so we try to make everything as easy as possible for the driver including a comfortable ride you can put the steering wheel exactly in the position you want two types of motion in and out and up and down and if I push this half way down I will get the neck tilt Hagerstown Maryland this is where the engines are manufactured one unit weighs almost 2,500 pounds approximately the weight of an average passenger car [Music] the engines are traditionally painted green production begins with the delivery of the engine blocks from Sweden the majority the vehicles are fitted with a 13 litre diesel engine we go by leader for all of our engines so all of our cars everything it's measured in liters yes the 13 litre engine is a six cylinder diesel unit and produces between 420 and 540 horsepower depending on the configuration an empty engine block alone weighs over 200 pounds firstly the block is given a number then it begins its journey along the factories assembly line the cylinders are installed by robots [Music] meanwhile two different machines sand and drill the crank shafts [Music] we have to drill it's all based on cycle time the cycle time is much longer to drill through the part than it is to mill the part we can build apart in four minutes it takes us ten minutes to drill it the crankshaft is the heart of the engine it's refined with an induction hardening machine from Germany that rapidly heats it to 1,200 degrees and then quenches it with cold water this makes the surface even harder and more resistant [Music] this is the result the crankshaft will convert the movement of the Pistons into rotational motion with the help of so called connecting rods thereby making the wheels turn it's installed in the engine block the next components to be put in place are the valves these are oiled manually before being inserted for four cylinder a total of 24 [Music] the cylinder head is put in position with the help of a crane the engine block is now complete [Music] it's transported to the next station by what's called an Ag V an automated guided vehicle which is basically a self-propelled robot it stops at every workstation in the factory waiting in place until the parts have been assembled before moving on there's a guide wire in the floor the guide wire is a way to communicate with the HV there's a sensor in the bottom ages V and it holds a wire and it follows it the whole way around the only time the edge UV stops is if you're in front of it there's a safety laser it will stop water Mackley or there's things in the ground called RFID tag where the engine stops for each station so we can do the appropriate work on to it well it's made it it can manipulation you're gonna see if moving and turning and that's again if that's for position for the operators to be able to build appropriately at each station in about three hours time the engine will be started for the first time but before that another 400 fixtures need to be mounted with the use of special tools [Music] such as this electric ring spanner which opens with the push of a button in the past the few line fittings had to be tightened by hands the electric tool saves 70 seconds per fitting the bolt is secured with one push of the button and a second push releases the grip so you can't get a normal gun on this because there's a line going in there so when he tightens it so how you can see I can't get it out because that gap as you can see there to the gap is over here I can't pull the line out so this gun is used it has a dual trigger figurehead bear so he hits it again I can pull it in and out there's a specific torque for each screw on the motor that's why employees use digital torque wrenches these record exactly which screw on which motor has been tightened when and how tightly all this information is sent to the central computer via Wi-Fi the bolts and nuts are first tightened by the workers with a conventional fast turning cordless screwdriver and then with a torque wrench the AGV only moves on once the green lights been given if a part is missing the engine remains at the station this 6-fold torque wrench is used for the crankshaft damper it tightens the six screws with the correct torque in the correct order this ensures that the damper lies completely flat against the engine block in the 13 litre crank damper we have six fasteners it's a two-stage torque so rather than doing 12 hits with a handheld torque on you do 2 2 cycles with this multi spindle torque on in the next step the engine is fitted with 4 oil filters three large ones and one smaller one the engine will have capacity for up to 36 liters of oil the oil only needs to be replaced every fifty four thousand miles the job of the filters is to keep the engines lubricated to do this they filter out any burnt oil particles along with dirt and dust from metal abrasions then comes the inspection at seven separate stations workers check by hands whether all the parts have been correctly installed the engines are about to be started the yellow agb's work is done from now on the units will be transported on a conveyer belt the engines now enter the factories test area before testing begins the engines are filled up with oil and other liquids [Music] while we're filling it we're rotating the crank rotates at about three rpms there while we're filling it it's rotating and pushing the oil into the cavities where we need it filling up take sixty Seconds my first test can begin a worker attaches pipes cables sensors and exhaust pipes to the brand-new diesel this is done on a turntable while that's happening another engine on the other side of the turntable is tested in parallel then the positions are switched the engine that's been tested is moved along replaced by the next one on the test stand [Music] I love this job I wouldn't want to not Nelson don't think it keeps you busy but I just it's just neat to do it and it's a challenge every day to try to stay on the same pace I really enjoyed [Music] each new engine runs on the test stand for four minutes there's no time for it to warm up which is why this is called the cold test during every shift at least one engine is randomly selected and taken off the assembly line this engine is put through a hot test tested for 22 minutes at every rpm range if everything's working the next stop is the paint kitchen all the engines are painted green any parts that shouldn't be painted are taped up robots spray the engines into paint booths a lot of rust preventative as well that goes along with it and also the customer side of it they do really like seeing that green engine whenever they open up the hood once the paint is dry workers remove the protective covers [Music] now the 13 litre v6 series six-cylinder diesel engine is ready for transport to New River Valley it weighs more than a ton depending on which production week it's earmarked for they will now either be stored for a few days in the warehouse or go directly to the shipping dock where it will be loaded onto a trailer [Music] Monday morning the early shift at the New River Valley plant is getting started more than 300 truckloads of parts have to be unloaded per day this is done at approximately 120 loading ramps around the plant only parts that are being stored temporarily are sent to the high bay warehouse all other loads such as the tires are installed immediately including the engines from Hagerstown forklift trucks take them directly from the loading ramp to the assembly station I have operators unloading wheels and tires engines and transmissions on both sides and then staging them into order sequence for the line you pick up the next one that's the next truck that's going down the line there's sequence from Hagerstown then we sequence them right here on the dock to go to the law meanwhile small parts are delivered in standardized wooden crates and brought to the high bay warehouse the plant requires about 750,000 cable ties every day so they're stored here in bulk logistics specialists distribute them in small quantities to the respective assembly stations the hive a warehouse consists of nine five-story shelf units seven of them are loaded and unloaded by robots two by humans a team of twenty warehouse workers constantly checks which part is where where it needs to go and how long it will take to reach its destination then it generates what we call a ticket this is a receiving tag a zip tag is what we call them internally this tells us parts are received now with the quantity and where it's going 58 so they'll take it and place it on the conveyor when it goes through that there's a curtain on the conveyor that reader will read our zip tag and it'll tell it where to take it in an open cell down here this basically has 10,000 142 cells in it so there's no way somebody can memorize where every packages in there each loading and unloading procedures recorded in the main computer to human operated cranes are responsible mainly for bulky goods larger crates that can't be loaded by the robot cranes the crane operator transports the wares from the grounds to a freecell unloads them scans and saves a ticket and the location then returns to the warehouse for another crate and starts the procedure all over again when material is needed in production the high-bay warehouse automatically sends it via this conveyor belts [Music] more than 1400 of these crates leave here of her shift they contain everything from radios to window regulator motors to headlights the warehouses were stocked at the same rate as it's emptied so that the shelves are always full we have five haulers per shift that do nothing but pick parts off of the end of this conveyer and they take it to the use point where the parts consumed on the line there is just over 15,000 different part numbers that go under the truck that's us moving a little over 850 thousand different parts a day to the line to be consumed still there's always a screw or something or other missing here and there that's where the so called hot part runners come in like Mike he feels emergency calls from the various stations and then fetches the missing parts every part however tiny is crucial to the production process [Music] they would myth and that would shut the line down and prevent the truck from continuing to be built mike has to know exactly where each part is stored he often has just minutes to locate it before production runs into a serious problem [Music] this is where the dashboards are fitted the mobile lifting platform means women can also work at the station women make up close to 25 percent of the factory workforce some jobs however are done exclusively by men such as installing the windscreens first rubber is stretched across the windscreen and wiped down with lubricant then a string is inserted into the rubber while the cord is pulled out from the inside a technician fits the screen into the rubber [Music] it's wiped down and the job is done the next step is to fit the seats it's vital that each seed is fitted into the right place there are 24 possible variations like the engines the seats are positioned on the conveyor belt in the order they're needed the door panels loudspeakers side windows and window regulators come next [Music] the cabin moves along the main assembly line at a speed of three and a half feet per minute it passes through 56 different workstations as it's assembled piece by piece including the steering wheel and storage compartments the workers install a total of 750 to 900 parts in the cab the large refrigerator is a particular highlights this is a refrigerator installed in the unit you can see it got a lot of storage space inside the unit for the driver it's really really good on over drivers that take it along over the road trips in the meantime the power supply has also been installed an employee now checks every single switch everything works perfectly but a stressful situation is brewing at the next station where the bunks are being fitted the crane is defective the bunks have to go in the trucks but the robot is on strike and can only be serviced when all circuits have been switched off [Applause] minutes pass the men look for a solution a bunk weighs 130 pounds and there aren't enough workers at the station to assemble it by hand the bunk manipulator has broke down on them and they're waiting on maintenance to fix it so they're either gonna try to get to get it fixed if maintenance cannot get it fixed we'll start installing bunks by hand we'll just bring extra operator in to help put those bunks in my hand it's hard work but they get the job done still it's only a temporary solution and the technician still can't get the crane to work finally the error has been found a bent safety bar now the team can get back to business as usual the crane lifts the bunk into the perfect position where it can be secured [Music] [Applause] [Music] more than 160 forklifts and transport vehicles are an operation every day at the factory stop signs that are operated manually ensure that people can move around the plant safely they have a lot of vehicular activity inside the plant they have virtual stop signs where if there's going to be a cross point between the lines you literally hit a button and a virtual stop sign comes on it stays off for 30 seconds to give time for the engine or transmission to cross over to this point the engines from the Hagerstown plants are now transported to the assembly line along the roof by wire rope hoist s' each engine is reserved to a specific truck a chassis is put in position then the workers carefully insert the 13 litre engine units once it's installed a huge coolant radiator is put in place [Music] forklift trucks transport four tires simultaneously from the delivery docks to the assembly line the employees then assemble them with the aid of small lifting cranes four tires per axle are fitted to the rear axles in this way the truck can distribute the weight of the trailer over several tires the wheel nuts are fastened with a cordless screwdriver so they're functionally tightened down five nuts at a time which again is designed to make sure we have the right quality verifications in place for that unit before it goes to the next placement now the cabin also leaves the ground and continues its journey through the air before it's placed on the chassis the workers install the air suspension this provides additional suspension for the cab the chassis is now prepared for the so called wedding this is what the men in the factory call the process of joining the chassis and the cab it takes just a few minutes to transform the two main components into an actual truck this chassis that's behind this three hours ago was just two steel frames being put together between there and then people have dressed the chassis put the axles on put the tires ningen on and now if it's preparing to have its cab deck the aluminum tank still have to be fitted they weigh only a few kilograms and can easily be mounted by hand depending on the configuration the tanks have a capacity for up to 300 gallons of diesel the cab is on its way the magic moment is approaching the workers carefully lower the cab and attach it to the chassis all plugs and connections have to be connected the crane releases the cab and heads back to pick up the next one [Music] every four minutes a new cab is set down and installed every four minutes a new truck is completed [Music] then comes the hood but trucks defining feature [Music] [Applause] American trucks are famous for their distinctive engine hoods European trucks don't have one there are several reasons for this on the one hand it's a matter of tradition but in Europe there's also a maximum truck length in the US that classic American adage still applies the bigger the better before the hood is closed the workers always knock on at four times here's why they knock four times on the hood because they want to make sure there's not any body inside the hood working it gives their colleagues and notice that they're getting ready to close the hood once the radiator grill is in place the truck is complete the final step involves playing the latest software version on the system and the vehicle is ready to go [Music] now it heads to a technical inspection the trucks are lined up in three lanes a driver's get them ready for a lap on the in-house test track [Music] 44 year-old mike maloney is one of the test drivers he was a trucker for over two decades he began working here four years ago and now tests between 15 and 18 trucks a day he vouches for their quality with his signature sticker for proof of my being the one driving it then we look over the pink sheet to make sure that we're all good to drive and what's been wrong with it and it's really abs has been signed off so it's good to drive and then we just walk around and make sure over both has been marked so they've been secured too so they're tight just make sure the whole trucks just safe I look at that truck like I own that truck and I know what the man wants when he buys it I've to make sure that it's perfect for him is perfect if we can get it mic checks the mounted components first everything has to open and close perfectly everything has to have the proper clearance and nothing can be loose [Music] each truck has to pass the visual inspection before it can be driven will climb in we'll have to finish up the the other worksheet for when we go to the track in the interior might test so that everything works as it should every button every switch every indicator light he has to fill out an official worksheet [Music] the test track is part of the factory premises another test driver is already doing laps he's known as ZZ Top because of his beard gas his driving technique is legendary no one can complete the circuit faster than he can yes there's a strict speed limit on North American highways Mike drives over that limit pretty often I get to drive more new trucks in one day than most drivers will grab their entire life I want to get it up to a certain speed right now I will check and make sure there is no vibrations I want to make sure that the engine brake is going to work which you can feel that when I'm in in a turn I want to make sure that the rollover valve is going to work and it will shut the engine down if I get in too much of a rollover a test drive comprises four laps covering about six miles when it passes the truck gets its stamp of approval and is ready to hit the highway and head to its buyer several hundred trucks are dispatched from the factory every day [Music] [Music] in Europe long-haul trucks are often shipped or transported on trailers quite because the distances in the US are so huge the manufacturers come up with a different system one truck toes up to three others and drops them off at the customers [Music] the workers mount an orange-colored coupling onto the trailer coupling the so-called fifth wheel and attach a truck to it [Music] the tow truck reverses and gets a few simple taillights that are easily connected by cable what at first glance looks rather provisional is extremely effective and saves costs after delivery of the last truck the driver doesn't have to drive back to the factory in a truck with an empty trailer [Music] as you can see the trucks are stacked and then after they deliver the last tractor which is the one that's hauled the others then that drivers gonna get an airplane fly back to the New River Valley and then be assigned the next truck so he will be delivering somewhere a maximum of four tractors can be connected to one another anymore and the convoy wouldn't manage to get around bends in the road every day 14 drivers packed their bags get behind the wheel and head out to the customers [Music] these three new tractors will be in Canada tomorrow [Music] our trucks actually are built for the North American market which is Canada the United States and Mexico so these drivers are leave here functionally can be driving 3,000 miles away or maybe they're driving 150 miles away from above the plants Welcome Center looks like a gigantic company logo [Music] a very special guest is visiting today [Music] Chuck Wilson and his wife might look like average tourists but Chuck is probably the plants most famous customer in the past 35 years he's probably bought more trucks here than any other customer [Music] when we sold a company we had about 750 so through the years with all the turnover it's several thousand around six thousand trucks in the company's trademark colors green and red have been delivered to Wilson trucking since 1982 almost every factory worker in New River Valley has worked on a truck for Chuck Wilson today Chuck's very first truck is on display in the welcome center alberene f7 built in 1982 that was my last day with the Wilson trucking yeah yeah instead of there buying a truck I bought a truck for $1 it's also the first Volvo truck manufactured in the US Chuck sold it back to the company for a token $1 first US production Volvo Wilson trucking corporation September 1982 yes you can see how the how this kept was kept up this is the original a few years ago we were trying to restore the truck son we've repainted the frame and so forth but it's in very good condition from the past to the future this is veera an autonomous driverless tractor [Music] the manufacturers engineers are already testing the first prototypes a concept is radical there's no driver's cab the engine is fully electric cameras and sensors are installed around the tractor birra is wirelessly connected to a control center which monitors location battery charge and other parameters the vehicle is intended for use in enclosed areas such as ports and logistic centers [Music] [Music] but plenty more trucks will be made at the plant in Virginia before Veera conquers the highways the long distances that need to be covered have prompted many truckers in the u.s. to give up their homes and actually live in their vehicles all year round like canon bet Zeldin their truck is well known across the country it's been dubbed Kermit for obvious reasons a couple love long journeys and that makes them popular with haulage companies with far-flung customers [Applause] in addition to the double bed at the rear the apartment has a microwave and two refrigerators and behind the passenger seat there's even room for Stacey the dog the couple has lived on the road for the past six years I'm proud when I Drive in someplace security looks at that name and he says there you can and I can say yes I am Ken this is Carmen [Music] John and Miriam brown on what's probably the biggest truck on North American roads they have invested a lot of time and money in their custom a truck it's basically a Motorhome with a trailer we wanted to travel we wanted to spend all of our time together yeah and it definitely fits the bill for both of those we'd plan to do it for a year here we are 14 years later as far as I know we're the only VL style Volvo in North America that runs the 20,000 pound steer axle and 425 steer tires you'll notice we've got the the rgn ramps for a removable gooseneck trailer as you can see the backs all been customized there's our ladder to gain access to the top where we keep our surfboards and things a two-room home with 500 horsepower all right here we are inside big screen TV that comes out on an arm to view anywhere you'd like our couch folds down into an extra bed this is the dinette it's on a slide out so when it's open we have a lot more living space in here and mozzie has her a little bit under there with all of her toys down here one of my very favorite features of the truck is our all-in-one washer and dryer coming into the kitchen I've got my double sinks and my two burner electric cooktop which is awesome after our first year in trucking we realized that if we were gonna stay in it we needed to find a way to be more active and make better eating choices yeah and we wanted to stay in that we loved trekking and we love trucking so this was the only way to do it for us every year we say well we still like it it's still a good good way to live a life so we make a good team yeah a massive hood a huge engine a spacious cab and a roomy sleeper the classic American truck 3,500 people work in the huge factor in New River Valley Virginia a new truck rolls off the assembly line every five to ten minutes more than 300 trucks deliver materials and components every day demand is huge 750,000 cable ties alone are used on a daily basis customers have a choice of more than 500 different colors for the cab and the chassis it takes just 12 hours to build a new truck with some 2,800 individual parts the final inspection takes place on the in-house test track every truck has to pass the endurance test over four rounds before delivery in the past few decades more than 500,000 trucks have left the factory in Virginia and thundered along the highways of Canada Mexico and the United States extra extra large trucks made in the USA [Music]
