We mounted angle iron along the bed rails, the two sides and the back of the bed. Built a frame out of pressure treated 1x2's. Went to a local sign shop and got some aluminite(two pieces of aluminum sandwitching corregated plastic, very light) scraps, in other words signs they had discontinued or was no longer able to use. Come in 4x8 sheets 3/8's inch thick. $20 for two sheets. Screwed it down to the frame, added a sheet of plywood underneath for strength and mounted it on the bed Plan on covering it with tonneau cover material bought online.
