I added a horse stall mat cut to shape as a bed mat. I've done the same thing in our trucks so that not matter what we haul, within reason, it will not damage the bed. I left out complete coverage in the furthest forward diagonal cutouts. The stall mats come in 4x6 sections so by skipping this area the mat will cover the entire bed and tailgate except about an inch of the tailgate. This also allow to use the tie-down points in the forward portion of the bed. While I like the idea of a hinge at the break between the bed and tailgate I like more there not being seam for crap to get stick into or for a shovel to get hung up so for the time being I will deal with the closing inconvenience.
