The only issue I have had with the slide, is more cosmetic, not mechanical. The side walls of the slide, both front and back, have "bubbled" the metal is wavy. I had the mechanic look at it at the shop and he said, "yeah, sometimes they do that. He didn't know why, but that sometimes they did." He also said nothing was leaking, scratching, tearing, dragging, snagging or ripping. I check them every time I run them out and they have not changed. I also check the rails, seals, and lube the rollers with the lube I use for my WD hitch. Works fine.
