Hi, does anyone no how to convert a 1988 Mitsibushi Canter truck which has aliminem panels, we are trying to get it so it is side loaded, I am just concerned that the aliminem won't be strong enough, we were told to use steel for the ramp and use steel for the framing of the ramp. Has anyone ever converted an aliminem box to a horse box before, if so, please let me know how to make it safe for the horses.
