I'm another very satisfied Lomax owner, for all of the reasons already stated. I will note that I'm not terribly mechanically inclined, and even I was able to install this tonneau with very little difficulty and very quickly. The only issue I had was with the truck, not the tonneau, in that one of the bolts was so tight that I had to take it to a shop with an impact driver to get it loose. I'll also note that three of the four doohickeys (that's the technical term, I'm sure) that serve as pads for the folded up panels came loose, but Lomax is shipping me replacements without any question, and I'll just make sure they're really glued down well this time.
