I installed mine in one piece on a GM truck. Starting at the top on one side working down, across and up the other side. Instead sticking it to the rear side I stuck it to the sides and across the top of the ridges on the bottom. It looks a little funky at the bottom (wavy) but it seals good. Also there is a gap at the top on each side. I filled that in with extra material left over to the side of the tailgate on each side. Just be careful installing across the ridges paying attention to push the material into each corner.
