rug vs spray in vs slide in liner

Thanks for all the recommendations. I guess it will be the spray in liner. I tried to call the dealer to see who they use but no reply yet. I will take my chances with the adaptor fit. I am usually pretty easy on my trucks. Never remember a inside out dent in the box. I was surprised to see how easily the floor of the bed scratched. Seems the paint might be a little thin. When I installed and removed the hitch to check fit I lined the bed with cardboard and after that the heaviest thing in the box was a couple coolers which slid around a little. Can't believe the marring it caused
