you mean to tell me you are buying a new trailer to haul scrap? should look into the possibility of a good used one.
That way when you sell it you don't lose too much on the depreciation.
I also agree with Mick, the car carrier is a better option, with the stake pockets, and the tilt feature. (mine's 16ft. with 5ft. dovetail)
Just bought it for 1500 bucks in good shape. Now gotta figure out what kind of removable sides to build when hauling scrap...wood or steel?
