Have figured that out by now :-) I am using a little bit stretched Version now in my survival world... The Cargo-Mass was a bit too much over the rear axles, so i set the Wheels one block more aft. Used the block to prolongen the "tanks" and slap in two more batteries. Work very well now :-) Thank you for the cool looking design!

Hello, the 1x2 slope block inside the wheel guards may prevent wheels from spawning

Hey I like the truck. Since the update I have a prblem with the wheels, it won't add them while building in survival mode. Not yet sure, wich blocks of the chasis are the colliding ones...
