I have one of those load handlers, and it DOES NOT work with the spray in liner I have. OK it works with a very small load, but put any amount of soil/gravel (when you really want the help), and the friction is too great for the load handler to overcome. The first time I learned this, I had quite a bit of shoveling to do (all while being careful not to cut the load handler sheet). I solved the problem by getting a 4x8 sheet of fiberglass paneling like you see in 7-11 bathrooms from Lowes. Whenever I go for a load, I put that sheet down first. It is much slipperier (is that a word) than even a plain truck bed, so the load handler works great, and can handle loads heavier than it was originally designed for. I have a shortbed, but its flexible enough to flex down in the bed with the tailgate up. When I open the tailgate, the sheet flattens out almost to the end of the tailgate, effectively covering the gap between the bed and the tailigate, so it really helps out. The only problems are that it cost almost $20, it has begun to crack, and its akward to store.
