I guarantee you would quickly abandon this double clutching "fun" at real trucking job because it is very tiring when you need to change gears a lot for example when there are a lot of intersections and turns. AFAIK most/all drivers in USA don't use clutch at all (for anything other than starting and stopping the vehicle) in non-synchronized transmission trucks for that very reason. Switching gears without clutch is easier and faster when you learn how to do it smoothly.

That being said... I strongly suggest you to try either American or Euro Truck simulator games. If you have a steering wheel and gearbox controllers for your computer, you can indeed have a lot of fun and gain some gear shifting and big truck driving skills at much lower cost than in real life while still having kind of real feeling.

I have a not-so-old Audi with a known-bad gearbox w/ faulty synchros and because it is a turbo you really can’t upshift in that band when/where the gears are lined up without losing too much power so I have learned to time how long I should wait in neutral (for the RPMs to drop) before completing the upshift. Non-sequential downshifting after slowing down from a higher gear is much harder though - you really have to play it by ear based off the sound/RPMs and the current speed both. And it’s a six speed with considerably less slop than the old Beetles used to have.

Those old beetles were just four speeds, pretty beefy gears. I never managed a good downshift though, I would cheat and very briefly depress the clutch so it wouldn't slip. Do it too long and you'd get that horribly expensive smell. I was dirt poor and got the car for free so I really couldn't complain. Baby blue. And it taught me to be very careful on wet surfaces with a rear mounted engine (took out a bicycle stand with it in front of one of the busiest coffee places in Amsterdam West, "Tramlijn Begeerte" (dutch translation of a 'streetcar called desire'). Funny little car.

I had an old Alfa Romeo that was fantastic overall but had a pretty terrible transmission, especially when cold. You do learn quickly how to get by. :)

If you have a turbo diesel it's a good skill to learn as you can shift smoothly while still keeping the turbo spooled up and not cause as much wear on the gearbox.

A big example:

> Another advantage of a conventional cab design is that the truck can be more economical. Surely they usually pull heavier loads, but if there were two trucks, one a cab-over and another one a conventional cab design, and they had the same powertrain and the same cargo, the conventional cab truck would most likely use less fuel. Of course, that is just in theory – in reality there are too many factors to consider.

I don't know... power, load and fuel economy is the kind of data that's extremely available about motor vehicles... this is something we can't figure out? Or were they just writing hearsay to push content and get clicks? ("Subscribe to our facebook. Loads of content coming soon!")

More important to fuel economy is maximizing cargo per trip, as having 20% more cargo in the trailer has no impact on aerodynamics and minimal contribution to rolling resistance and acceleration losses. This is the main argument against the length restrictions in the EU. Longer trailers + more aerodynamic tractors would lead to a significant increase in fuel economy - albeit at the cost of road safety: EU records nearly identical deaths per year for trucking related accidents as the US - around 5000 - but has 300% as many trucks on the road and 50% more population than the US.

I think this is a very uncharitable interpretation. It has been decades in the US and Canada since cab overs fell out of style and thus you can't buy ones that take the same trade-offs as your average conventional truck. Comparing trucks designed for completely different regulatory, geographical, and practical constraints isn't going to net something useful so we have to make estimated guesses. It seems like it would be similar to comparing the fuel economy of an an unladen F-150 with an unladen F-350; They might do similar things but in practice there are so many capability trade-offs that it isn't a particularly interesting thing to do. As they said:

You're not alone! I have the exact same desire.

I have a lot of friends that are recreationally pilots or boat captains so I don't think it's that strange.

Look out. I know a guy who caved in and learned. Then decided he doesn't like computers all that much and he doesn't _really_ need that software engineer salary, especially if he can cut on rent by sleeping in his truck.

There's something appealing in the physical labour of feeling and manipulating the clutch and gearbox, that a simulator might not capture, but I will it check it out.

The opponents don't move, there is no clipping of obstacles, and once you cross the finish line you are greeted with a screen proudly saying "You're Winner!"

Obviously, the game developers were unexperienced and couldn't deliver a functioning product. What's amazing is that the company had the audacity to sell it in stores nevertheless.

Driving a road ranger gearbox is a lot of fun. And a jake brake makes an awesome sound! I agree with the comment below me - you almost never use the clutch, just match revs to gear. It’s a nice skill, you can do it in any manual vehicle but you’re more likely to torch the transmission in the average car - Toyota landcruisers are good practice though

EDIT in response to reply: I actually don't think it's obvious that if you get C, M1, and A separated by a month that you should do 1+2+3 tests but that if you get C+C separated by years you do 1+0 tests.

I once had a commercial license paid for by a grant program as part of that job. I had to give it up when I moved states and no reason to redo it. I regret it a lot because it was useful in many ways. Probably different in Australia, but having a odd set of skills never hurt my life.

I suspect you could find a Formula Dodge or Formula Ford racing series with an intro class if you just want to learn the gearbox aspects, plus then you can learn to rotate a car with the steering wheel, the gas, and the brake pedal. ;)

I wouldn’t get the license though as even minor traffic violations can become a pain in the butt.
