hey guys, i need some help here. So i was looking into a toyota truck with a dually and a box to transport large boxes that dont weight that much. I think u-haul has some of these, and i hope you guys have seen them so you can understand what i am talking about. However, i read that toyota only made dually axel in the 80's, they are hard to find, and expensive to find parts. So i was thinking of getting a regular toyota truck, and somehow putting a 8'x4'and about 8' high metal box instead of a short bed that tacos or t1000 have. Has anybody tried this? any suggestions? Can this be done? Would it be safe? How expensive would it be? thanks so much!@
