Nice cover, still seems a bit pricey.
The cover arrived in one large box without any damage. Rails were fairly easy to install -- they bend to the concave Ridgeliner walls as you tighten. I recommend test-fitting before tightening to adjust fit to tailgate. The cover itself is pretty easy to install, two people would make it even easier. I found that the rails impede the side-opening tailgate and gouged the plastic. I adjusted the rails higher and shaved a bit of plastic from the corner and it works fine now.
