Thanks! It was actually inspired by this: From Eoin McNamee's book The Navigator. That thing is called a Q-Car, and it's the only bit of the book which stuck out to me. I didn't make the cabin because of part count restrictions. Feel free to use, adapt or otherwise take my designs. Hmm, that's not a bad idea, it may be hard to get it to bend without sagging too much. Thanks! No, it doesn't. I almost added them after taking apart your mega truck, but I would have had to put the crew compartment even lower, plus, it's already completely useless since it can't steer, so it might as well be fuel inefficient too. Thanks!
