I currently have a 2003 ram 1500 4x4 4.7l v8 with 114k miles on it. I was wondering if I could swap everything over, engine, trans and cab to a 2500 frame and keep the 4x4 and keep everything the same inside the truck computer and wiring wise. I know where I can get a cheap 2500 roller frame. I'd use the 1500 title but is there any problems I'd run into? Would 4x4 work?
