That is a drop in polyethylene liner. I used the same plywood in the '99 truck which had a spray in liner. It too had a poly liner to start, the camper shifted (admittedly in challenging conditions) so following some advice here I removed it and did the Line-X spray in. The camper moved just as much, hence the plywood with blocks or rails. In the new '15 truck, I went back to the poly liner as they protect the bed better than the spray in. Sadly, the poly liner (same brand and model) now is about 1/2 or 2/3 the thickness of the old one. That makes it a little "softer" under the load. With the plywood though, it is still not an issue - the load is spread over a large area of the liner and bed and there is no difference in movement compared to just the steel bed.
