[@MrGrumblier]

@@carkawalakhatulistiwa Rail lines are great to go from port to distribution hubs, but if you want to get a variety of products, like groceries, to a bunch of supermarkets, trucks are the only way to do that. In Canada, for example, we have major ports in British Columbia, Nova Scotia, New Brunswick, Quebec, and, to a lesser degree, Ontario. To get cargo from Vancouver that is destined for Alberta or Saskatchewan, it goes by train to various distro hubs then it is sent out to company distro centres like Wal-Mart or Auto-pro by truck then sorted into loads for specific stores where it is again sent out by truck. A train is great for moving a few thousand TVs, but moving 10 or 20 TVs, pallets of can food, pallets of pillows, and clothing works far better on a truck even over 1000s of kilometres.

There used to be a lot more generational drivers, like myself, that learned at a young age and guys like me helped those new drivers learn the ropes. Now you have drivers that have very little experience teaching new drivers with no experience. The fact that you believe that automatics are better just goes to show you were never taught properly. No matter the innovations with automatics, they have massive downsides, especially in hill and mountainous areas. They are especially harder to control when backing. It all comes from who taught you. If you worked for one of these big companies like Swift or Werner, then you were likely taught by either another inexperienced driver or a driver that was also taught by another inexperienced driver. It’s a chain that creates more and more bad drivers.

[@alexclement7221]

Tag axles: You missed a couple more reasons, like a) Toll reduction; some places charge trucks by number of axles on the road. If you can legally carry your load with the tag axle lifted, you will pay a lower toll. b) Makes installation of tire chains easier. On SOME trucks, the tag axle can be lowered so far that the drive axle can be at least partly lifted, which makes makes it a bit easier to install the tire chains

[@crazytrain7114]

[@alexclement7221]

Depends on the axle and the jurisdiction. In the US, a "single tag" will only add an extra 12,000 most places, some places more if it's a wider tire, making for a 20,000 drive axle and a 32,000 tandem total. Dually tags are just the same as a dual-drive axles, at a full 34,000 tandem. Axle loads are higher in Canada and Michigan, and in Mexico, they don' need no steenkin' scales.... @@Jay-gz6mv

[@davidnorthrup3674]

I have done a lot of mountain driving in Colorado. And I must say that the main reason I prefer a manual transmission is for the hills, both up and down. Going up hill it is easier to keep the truck in the correct gear for the hill. You have only limited gear selection in autos. And most importantly, a manual transmission holds a truck back better going down hill with the direct connection to the engine. The reason for the added cost of manual transmission maintenance is due to lack of driver knowledge. I drove a manual in the mtns for 3 years with the same truck and clutch. The only reason it ever needed a clutch was when I went on vacation for 2 weeks toward the end of that time and an inexperienced driver burnt the clutch. Now all my companies trucks are automatics. Thanks for the video!

[@Coonazz791]

That’s so true. I’ve had my truck for 6 years now and I’m on the original clutch and the gears are still tight. Plus, I’m still on the original brake pads which have 618,000 miles on them and can probably go another 500,000 on them. There’s a lot of maintenance issues you can avoid just by knowing how to do it.

[@bfgoodrich8564]

Having a manual transmission is a must on bad roads. The arthritic chimpanzee they have shifting gears on the automatic doesn't know how to shift when traction is so poor, the tires are spinning. Putting tire chains on confuses the system even further, as it will not shift at all when pulling a grade on icy roads. Not even in the so called manual mode.

[@curbstomp3126]

I ran 10sp 13sp 18sp and even a two stick Mack. I started driving a 12 speed auto a few years back and it's a wonderful transmission.

[@TopiasSalakka]

Automated manuals all have a manual mode though, you can just put it in M and hold a gear for as long as you want. Some also have hill modes or even offroad modes for their automated manuals, i drove a Volvo FH dump truck with an offroad mode and it was great in snow dumping sites, along with the automatic diff locks.

[@independentpolicy3247]

Longer wheelbase have better ride characteristics. It's the same reason that riding in a train near the axles is rougher than in the middle of the car.

[@oldeenglish8058]

A couple more items come to mind. Engine capacity has a direct effect on the effectiveness of it's braking power or Jake Brake/ Jacob's brake. Invented by a log truck driver in the western usa it reduced the number of run away trucks after excessive braking (brake fade) from descending long down hill runs (mountainous terrain) The bigger engine capacity provides so much braking effect with the correct down shifted gear that you can descend hills without using the brakes at all. The second thing I thought of was the pro's and con's regarding transmissions. There are many drivers out there that do not know how to shift gears, or even how to use the clutch from a standing start. The wear and tear on the clutch, transmission and power train is very costly, not only in repairs but lost revenue due to the truck sitting in a shop waiting to repaired. Many experienced drivers will only use the clutch to get the rig rolling, then all shifting is done without using the clutch. I put 600,000 miles on a new Kenworth Sleeper with a C15 Cat engine and it still had life in it when I retired from that company. The terrain varied from flat land to over the Cascade Mountain ranges. Stay smart and stay safe out there! All the Best!

[@patrickloomis992]

There's a 7 mile downhill run on I-77 going SB from Virginia into North Carolina, fully loaded, in the right gear, with the right level of Jake brake, I can just glide down at 55 without touching the brakes or the accelerator.

[@oldeenglish8058]

Way to go! That is the smart way to drive down hill. In Washington state I frequently travelled Snoqualmie, Blewett and White Passes always picked the best workable gear and jake brake for the load behind me. Nice to know you'll get home safe at the end of the day!@@patrickloomis992

In 1980, when I was a Sophomore in High-School, I penned a Truck-Cab eerily close to the TESLA COE Tractor, back when NO ONE considered Aero, Fender-skirts, or retracting Pin-Tables. My design was a 'Tilted into-the-Wind' Cab-over that created a 'nose-cone' of decent streamlining, and allowed a Shorter Cab than front-engine set-ups, but had enough 'track length' to be stable (not Darty) with long trailers. The Cab, now being above, but a bit Behind the Motor, could be de-coupled from the engine noise/vibration/heat, and, like a Cab-Over, the 'Storage + Bunk' space could be quite Deep, as well. Having a retracting (on a hydraulic ram) Table for the Trailer Pin, meant that the Cargo could 'reel-in' to tidy-up the Airflow on the Highway, but also extend to help in 'tight alley' turns, or for Stability with high C--G loads in corners. I used Full Skirt fenders to streamline, but also keep spray/dust from Harming Cars as they drove nearby. The Fuel-tanks were also 'flared' into the fender skirts (w/steps to access the Cab/front-of-the Trailer) to further streamline the Rig. In the Doors, 'Look-down' glass panels let the Driver see small cars tucked-in close to the front-of the Cab.

Diesel is a lubricant, gasoline is a solvent. Less wear on cylinders and rings burning diesel

[@moseshughes2670]

Actually, sulfur is a lubricant, and modern diesel fuel has very little sulfur compared to fuel 20 years ago. Also, fuel doesn't lubricate anything in the cylinder. It burns. Diesel engines have reduced wear vs. gasoline engines because of how they are designed, not because of the fuel. And, furthermore, diesel contamination of engine oil actually INCREASES wear, and contamination is more common now due to the use of post-combustion injection for the DPF.

The people that decide we don’t need higher horsepower in the US hasn’t ever been behind the wheel of a working truck, just test tracks. The limited horsepower has more to do with companies here wanting to spend less money on the trucks not caring how long it takes or frustrating it is to climb a hill or mountain while still pushing you to make the delivery on time or ahead of schedule. They also don’t really care about driver comfort because the seats in most trucks unless modified really suck and the options within the trucks are very limited and sparse. The legal limit in the US is 80k but that doesn’t mean that drivers don’t often haul much heavier loads with the proper permits. The EPA also has a big hand in the engine choice here in the states. Just another example of them sticking their noses into areas they don’t belong because a lot more to concerned about than what engines we use.

[@Hay-x7p]

You're right about companies not caring about how long it takes you to make your delivery. As long as you're not late to your appointment. They pay mileage for a reason. They also want to get rid of all their drivers as soon as possible, replacing them with driverless trucks. Robo trucks won't have hours of service regulations to follow. They won't have to be paid or be provided with benefits or days off. Those trucks won't take sick days or vacation days and will only stop to refuel, load/unload and have maintenance performed, the occasional flat tire not withstanding. Those trucks won't speed or get distracted or sleepy or p¡ssed off. They won't jam gears or get into accidents either. And they won't organize or demand more comfortable seats. They'll effectively be slaves. The day of the long haul truck driver is in its sunset years. Local and specialty drivers will have a few extra years before the hammer drops, but not many. Just don't let your kids become truckers. They'll never get to retire doing it.

They’ve hit several vehicles including emergency vehicles while they are parked on the side of the highway. Just imagine how bad that would be if it had been an 80 thousand pound truck. Personally I don’t want to be on any road with driverless vehicles at least for several more years. None of the trucking companies will be able to work on their own trucks as they currently do so that will cost them a ton of money and even more down time while waiting in line for service. They’ll have to pay someone to man every charging station because a self drive truck isn’t going to plug itself in. Companies won’t be able to force their EV trucks to drive faster in order to deliver ahead of schedule. Good luck replacing those massive battery packs when they fail because they will fail as well as start degrading year after year. Average cost for a car EV barttery is between 15-20 thousand. I’d imagine the Truck batteries to range in the 75-80 range. Who’s gonna take the straps off the flat bed trucks, stop after 30 miles to check the load and the toe downs to make sure they aren’t lose? Guess they are gonna have to man them with the fictional Tesla robot as well.

@@P-J-W-777 technology continues to improve at a geometric rate. Human decisions are being removed from the driving process. After 23 years driving trucks in Arizona, I moved to New Mexico in 2014 and drove oil trucks in the oil fields. Every single semi I ever drove over thirty years was a stick shift. When I moved back to Phoenix in 2021, auto shift trucks were standard in the industry. I didn't even know that technology had been worked out. I'd always heard it was too expensive and the automatic transmissions just weren't strong enough to handle the loads. They still aren't. So the manufacturers figured out how to get the truck to _"shift itself"._ The transmissions are still non-synchronous, but the computer system has taken over shifting duties from the driver. I started driving for Penske occasionally, moving empty tractors from place to place. None of the late model semi's they rent are stick shift and none of the newer box trucks are either. One of the guys that works there handed me the keys the other day instead of driving the truck up for me. He said he couldn't drive a manual transmission truck. I felt bad for him, but there just aren't any stick shifts on the market anymore. My point is that transition to automatic happened in less than a decade while I was gone to the oil fields. The transition to driverless will be just as rapid once the bugs are worked out. It's going to happen because MONEY. Driver compensation and fuel costs are the two biggest expenses in the trucking industry. If they can eliminate one, they'll do it. Driverless can happen without electric. Once both technologies are available, it's a win win for trucking companies. No more expensive fuel and no more expensive drivers. You can BET they'll do it. Amazon will probably lead the way. They'll invest in support staff to keep the electric robo trucks rolling. People will be used to facilitate that focused effort. Loading, unloading, mechanics, fueling, recharging, repair etc, it will all revolve around keeping the robo trucks wheels turning. It's going to happen, probably before this decade is out.

[@DeathHead1358]

The only 2 stroke V8s were made by Detroit Diesel, in the form of the 8V-53, 8V-71, and 8V-92. There quite a few other V8s out there, such as the 903 and 555 made by Cummins, the D336, 3150, 3208, and 3408 made by Cat, and the E9, 864, 865, and 866 made by Mack. I believe the Detroits were the most popular, followed by the E9 and 3408. The 903 was an alright engine, as well as the D336. General consensus on the 555 Cummins, 3208 Cat, and the 860 series Macks wasn't very good. 3208s are regarded as a throw away motor, 555s like to blow up if you lug them to hard, and the 860 Macks liked to crack heads. The mighty 3408 was know to break cranks when turned up to far as well, some attribute that issue to it also being a 60 degree V engine. I don't know much about the D336 other than it was a dozer engine that was used in trucks under the 1676 designation, and 3150 was a predecessor to the 3208.

Extra axles are not necessarily for grip on trucks with 3 axles it's about weight distribution. They carry more weight so the extra axle allows them to do that and not get weight violation or have to buy expensive permits. However, permits are the cheapest option if it's a one time thing for the weight. You have to custom order with more axles which is more expensive and most people don't do that unless they intend to haul the weight on a regular basis. Now on the trailer that gets tricky. There are a lot of configurations. If it's a 2 axle trailer you might see one axle raised if they have that ability when it's empty. This reduces friction and increases fuel mileage. Especially if it's a spread axle, see this a lot with flatbed. In Michigan, this is a great example for multiple raised axles, you might see that when those scrap metal haulers are empty. They also raise axles when they turn, tires will pop off the rims if they don't lift the axles when they make a turn. They have control box in the cab of the truck to do this. The reason the trailer has all the extra axles is weight. Those trucks haul double what a regular truck hauls. However that is legal in Michigan but you can't do that with 5 axles.

[@linonardin9629]

Having driven both manual and automatic trucks in the US, I have two problems with automatics 1) Since they're so easy to drive, it makes it easier for a trucking company to replace you; the skill level to operate a truck is lowered, which means that trucking companies can get away with more BS such as low pay rates, poor home times, etc.. , because if truckers start showing any signs of revolt, they can just be easily replaced 2) Since they're so easy to drive, they're also easier to steal. Truck jacking has been an increasing problem in the trucking industry, since trucks have been made so easy to drive. Sure, training drivers will cost more in the short run because truckers will burn more fuel and damage the transmission while learning, but at least your truck can't be stolen by any idiot with a gun. The second company I drove for completely forbade sleeping in a truck stop in Atlanta or within 100 miles from it. This wouldn't have been as much of a problem with a stick I do agree that automatics provide better torque and fuel economy, but if I had stayed in the US and bought a truck, I'd stick to a stick so it's less likely to get stolen If anyone reads my comment this far, I am not trying to change your opinion, I am just expressing mine

The automatic free wheels, so I had to learn to keep the left foot on the brake.

I was very much embarrassed by my dilemma, and had hoped no one had noticed. When I hopped out, another older driver came up to me and asked, "That is the first time you have backed into a dock with an automatic, isn't it?" He had driven his first auto just a few months early, and remembered the pain of looking like a rookie. I stayed with the older trucks for awhile, but changed from P&D to a meet and turn route with enough miles a day that a new truck was mandated. I ran 500 miles a day to the west and back, and another driver then ran the same truck and load 500 miles to the east and back which was another meet and turn. This was all in one twenty-four hour period. All the new trucks were automatics, but there isn't much backing to a meet & turn operation, so I was in good shape till I retired.

With experienced drivers a manual is a great choice and owner operators prefer them because an automatic cannot predict road or traffic conditions and will give better fuel economy and life span .

Torque is not 'pounds per foot'. It is 'foot pounds'. Foot pounds is a unit of measure of torque. It results from multiplying a force by it's distance to the point of rotation. If you increase either the force or the distance you increase the torque. That's why the unit is foot-pounds. 'Pounds per foot' imppies the unit is pounds divided by feet but it is not, it is pounds multiplied by feet thus giving the corrent name 'foot pounds'.

30:40 What the fuck is a "speeder"? You mean Throttle/Accelerator pedal. You make it sound like there is a speeder button on the dash. Maybe that's the button that goes to ludicrous speed! As a manual transmission driver, I would say that the automatic makes you more lazy, more easily distracted from driving. You need to pay attention to those around you (esp. in a big rig) in case you need to downshift or go into neutral/clutch to not kill the engine in an emergency stop. Another reason the manual has benefit, downshifting to help slow down. There is a lot of shifting, from a stop, in a loaded big rig, so city driving will be where the most shifting while happen. Once you are up to speed you only need to shift for grades, or to slow down/speed up. Automatics must be told through programming and have some form of Manual input to downshift/upshift at the proper times. This tech I am sure has made improvement over the years, but the computer can't see the road and traffic conditions (yet). Automatics also have a metric ton of slip, increased wear and service over a manual, they generally weigh and cost more (at least in the Cars and Trucks). Automated manuals MAY be a good compromise, I don't know much about them. The skill level bar to drive a big rig manual transmission, may be providing better drivers to the industry (total speculation). God Save The Stick Shift!

[@hansjansen7047]

That bit about not seeing the road is now obsolete. Freightliners now can gauge their speed , on cruise, so that they can coast up the last of a grade and take advantage of the upcoming down grade to resume cruising speed. It's done by GPS grade mapping of almost all major roads. Scary !

When it comes to trucks, any question that asks "why?" is always about fuel efficiency. The two biggest costs for trucking companies are fuel and driver compensation. They're trying to get rid of the drivers and let the trucks drive themselves so they don't have to pay the drivers. Slave trucks are a far better deal. Plus those driverless trucks will be far more fuel efficient than human drivers because they will never get in a hurry or get impatient or over-rev the engine while shifting. Higher power is also irrelevant when you can simply gear down. Raising axles is only about fuel efficiency and less wear and tear on tires and gears. I personally don't like driving auto manual trucks. They're not automatics, it's a different technology. The transmission is still non-synchronous, so the truck manually shifts itself. It's disconcerting. I'd rather do it myself. Cabovers were a pain to drive, especially locally. Climbing in and out was a hassle and the stubby gear shift with all the joints in the linkage was a pain to shift. The one I drove decades ago was an old truck. The modern ones out of Europe look fantastic. They probably are far more enjoyable to drive than yesteryears cabovers. Once trucks can drive themselves, manufacturers will put the drivetrain in the trailer and get rid of the cab and tractor completely. That way the trailer can haul more freight by increasing cargo capacity in areas with length limits. All wheels will steer, increasing maneuverability. This will absolutely happen once electric motors and batteries are perfected for heavy trucks.

I said no. Give me the 2014 Mack with the 18 speed manual you tested me on. They scratched their heads at that. It rode rough, it was noisy and I loved it. On the safety /efficiency score, I was consistently scoring 100% just about every week and never less than 95%. Well, they decided to retire my old Mack and gave me a brand new Freightliner with an automated manual 12 speed. Guess what happened? My driving score now sits serenely at about 78% to 82%... No bonus for me. Liquid loads move. You're trying to accelerate, the load sloshes backwards and the truck thinks oh-oh, there's a big hill here so it down-shifts on you... oops! "Hard acceleration! Oh, you aren't driving efficiently. I've tried it in "manual" mode too, but the computer over rides you if it thinks you aren't doing things correctly. Best driver score I've had on this transmission is 92%. That equals reduced bonus. I average 85%. This is not even getting into winter driving... that's another whole story. My conclusion, automated manuals are fine for dry freight, but for live loads like bulk liquid or livestock.... give me a good old fashioned manual any day. Way more control on icy roads and way better fuel economy for live loads. I miss my 18 speed manual Mack. I got a tear in my eye the day it was sold.

Did some driving in the mid to late 1980's. Finally got back to the trucking industry a few years ago. Do I ever hate the auto's. Dam things will upshit going down hill. Drove t680 & cascadia doing stepdeck & flatbed. The freightliner auto was way better. I got so sick & tired of the micro managing, by desk drivers, calling up and reaming over telemetry. Or something they saw in the camera. Why did you hard brake, to not kill the stupid fuck who turned in front of me. Got my own authority, W990, 18spd manual, 565hp, 1850tq, no governer at 65mph. Pulling 53' stepdeck. Walking through tall corn now. Manual 18 spd & No dipshit desk driver telling me how to drive!

[@marcgoff7881]

Your just a driver. When the word is sent down from on high ( Accounting Department) you should be happy that men much smarter than you are making these decisions. They probably have years of over the road experience (Actually they have never driven a “Brick and Mortar Truck”) but have qualified on a computer simulator. So when you lay your head down to sleep tonight you can be comforted with the knowledge The Accounting Department” has your back.

17:00 an inline 6 engine also runs smoother than a V8 engine, which is important for a big, low revving engine.... the inline 6 arrangement makes all the pistons move in pairs of 3, and the movements of the pistons cancel each other out... the inline 6 will not rock side-to-side like a V8 engine will

[@dudeenglehart6517]

As much as I love semis and a lot of the facts in this video are correct the V8 portion is very biased and or not correct at all. The overall fact is inline 6 is used because of the overall Mass on each cylinder can generate higher quantities of torque typically but a great example of why you might want a V8 versus inline 6 look at the 67 Cummins 67 powerstroke around the same displacement despite a couple of cc's of displacement but the 67 powerstroke has a higher output. One of the actual things said in the video was talking about how diesels use two cams instead of just the original one. That fact is completely wrong and it is up to the manufacturer to choose the proper valve train design for the operation of the engine to be efficient therefore if you see an overhead cam diesel is most likely meant for a higher revving application and one of the last facts I heard that was correct was the V8 is more complicated as it has more moving parts therefore the inline 6 is a lot cheaper an overall fine for the application the main reason you don't see a V8 diesel in semis anymore is because the cost of manufacturing

same with European Tractor heads trucks They Have Rear extra middle steerable axle provided which is' Midlift 'when its called" some variety of european trucks do it

[@marshallmcdonald7309]

Diesel engines in semis DO NOT get better fuel economy. Rarely more than 8.6 mpg. We go hundreds of miles between fueling because we carry hundreds of gallons of fuel.

[@TopiasSalakka]

Diesel engines do get better fuel economy than gasoline engines, that's just a fact.

[@jamesanderson2176]

Torque is NOT what allows trucks to maintain speed on a grade. That is HORSEPOWER. Torque is only a force. Unless that force can be produced at a sufficient rate, you'll have to gear UP to maintain speed, which divides down the torque. Horsepower is force times speed.

[@shadowopsairman1583]

Torque is needed to get heavy stuff moving, and to climb, without it you are wasting work

[@rickcorey5908]

I have always heard that horsepower is how fast you hit the wall while torque is how far you move the wall.

[@allenking4682]

And for god's sake, please get the units correct pound-feet! Not pounds per foot! (The announcer, not @jamesanderson2176. I added it here because you were talking about horsepower and torque)

[@bertpenney3526]

Exactly true! Virtually everything stated in this video about torque is wrong. Even when referring to torque generated by a diesel vs a gas engine. No, diesels do NOT generate more torque than a gas engine unless they are designed to do so. Aviation piston engines are almost all gas engines and they have torque and HP curves almost identical to diesel engines. Why? Because that is how they are designed! Propellers become very inefficient at high rpm so the engines are designed to have a redline of anywhere from 1800 rpm for the large ones to around 3000 rpm for the smaller ones. So a diesel engine with the same HP output and rpm limitations as a gas engine will put out exactly the same amount of torque. The type of fuel burned is irrelevant.

[@bertpenney3526]

@@shadowopsairman1583 No, it isn't. If it was, a vehicle powered by a turbine engine wouldn't be able to tow a baby carriage because it produces very low torque.

[@Chetbenton-jp5ip]

on the topic about trucks using diesel. the diesel also helps lubricates the motor. also the inline six is easier to rebuild and also lasts longer

[@Chetbenton-jp5ip]

also the auto transmissions especially Detroit there is no rebuild u buy another while with a Manuel trans u can rebuild the trans.

Most western states not called California allow trucks with enough axles to roll along at 105,500 without a OSOW permit. Additionally with the amount of OSOW loads are increasing continuously. I haul heavy equipment and regularly roll down the road in the Pacific Northwest between 140,000-178,000 lbs. We could really used more horsepower and torque in the long mountain grades we encounter in the Cascade, Blue and Rocky Mountains (just to name a few lol). We need Detroit or Cummins to come out with something 700+ hp and 2500 ft/lb

[@danw1955]

Having a manual transmission and a jake brake is almost vital in mountainous country to keep from losing your brakes with a heavy load. I've seen a lot of automatic and semi-automatic trucks on the 'runaway' ramps as a result of losing control due to insufficient engine braking. Also, we're NOT on the cusp of an EV switchover for heavy haulers. We just don't have the infrastucture to support it, never mind the lack of range for over-the-road hauling. The battery technology just isn't there yet. Kenworth has already quit offering electric trucks as of the beginning of this year, because they're too expensive to manufacture and maintain, and a lot of the outfits that bought them are turning them back in for diesel-powered replacements.😐

[@AlexKall]

You can have an automated transmission and "Jake brake" as well as a retarder.

[@Alfadragon17]

Some extra info on why diesel engines produce their peak torque values low in the RPM band. To put it simply interia. A big heavy piston and con-rod moving quickly takes a lot of energy to change directions. During an over-rev or runaway situation, these stresses peak stretching the conrod to the point of breakage. Combine heavy piston assemblies with a long stroke and you have a disaster waiting to happen. Thats why Ferrari engines can reach such high rpms; their engines are as light as possible. Their strokes are short. While a diesel truck or worse a diesel train engine cannot do so. Train engines are so big and heavy you can over rev some of them at 1000 RPM!

[@glennso47]

6 cylinder engine has fewer parts than the v8

[@kennethboyer2338]

Not just that but the inline 6 is usually very well balanced for some reason.

[@darrenwebb5334]

I6 engines are better balanced, lots of torque, fit in between the frame rails easier and main bearings last way longer than v8.

[@robertcook3961]

The main reason for lift axles is taxes. The truck pays road tax per axle. When light or empty, they raise the axle so they are not taxed on that set of wheels.

[@sergeantpeppers8858]

"...also, longer wheelbases can make backing up more challenging, particularly when the driver needs to maneuver the truck in reverse." How else are you going to back up a tractor trailer?

[@oldeenglish8058]

Explanation ... with the rear tandem axle raised it shortens the tractor wheelbase which also makes the tractor turning circle smaller. So when backing a trailer the steering reacts faster to steering input ... hence easier control over the trailer and reduces the need for pull ups to reset tractor/trailer angles.

[@harveydelanoy2430]

@@oldeenglish8058 Sorry longer trailers are easier to back up you can control the direction of the trailer because the reaction of steering input is much less compared to a boat

[@maxmoreno5891]

The worst thing for backing was power steering back in the day you didn't see guys backing in like a snake. It was more about setting up properly. Today they rock the wheel excessively and resemble a sidewinder when backing up up also so few of the aim the wheels on the trailer. They aim the box. Never learned properly.
