I made it scale, so that it can be used as a reference. If you want to make creations that interact with the convoy trucks, you don't have to look out for the convoy every time now, you can just use this replica. However, it is not a 100% copy. Especially weight, power and wheel traction can be different, so I would recommend using the real convoy trucks for final testing of your creations. You can also use it just to drive around of course, do whatever you want. I made the wheel suspension pretty comfortable, so that it doesn't bounce all the time. Also it doesn't tip over as easily as it did before.

Throttle is controlled with Pitch and steering is controlled with Roll. The engine sits in the cockpit, in case you want to change throttle control.
