1. The assemblers drove their screws to hard into the plastic case, cracking the case. 2. Missing shims. (they sent some in the mail) So quality assurance just let it slide. Once installed it kept popping open. When I sent a message to support at Leer, they responded like I was idiot highlighting sections of the manual discussing the shims. Ok so I missed that 2 or 3 lines in the manual, you do not have to talk to me like I am completely dumb. Now here is the thing, I kept adding shims, it kept popping open. The last shim I added stopped it from popping open but now the last 8 or so inches drawing it closed are now binding with the cover, you have to apply force to close it and force to open it but hey it does not pop open while driving! :) It looks great on the truck, it just does not function like it should. Being on the edge of working / not working based on one shim and they (Leer) talk to me like I am an idiot. Bottom line, they wont care about one bad review. After using a competitors roll cover for 7 years I am disappointed I ordered this one.
