hey guys im new to this forum and well, i like stuff out of the norm, like really out of the norm. i found a short bus for a very cheap price in good condition, one based off a c3500 dually. yes a yellow school bus. here is my idea, get a single rear wheel 4x4 frame. would it be hard, even possible to swap a 4x4 frame in place of a 2wd? it would be the one of the coolest rides at the mud bogs i think.
