2014 6.4 2500 - Bedliner was done at the factory. It's held up okay, I suppose. I throw a folding ladder in/out a couple times a day and there are some chips on the tailgate. I have a piece of plywood in the bed. My Rhino liner in an old truck held up about equally as well. Keep in mind this is a truck... things will dent and chip during normal use. I don't see how this is somehow a "defective" product that should be covered under some warranty but that's just me. This seems like going after the manufacturer of a helmet for showing scratches. The point of the liner is to protect the bed from damage. It will show some signs of wear along the way.
