The high quality of the components was a pleasant surprise. Even the hardware is good quality. I know this system isn't designed for it but I'm trying to install this rack system on my 2017 F150 with a 3 section hard top bed cover. I found a way to mount the side rails by using the rear stake pockets but drilling an additional hole in the front to mount with a bolt, this was tricky! I also noticed the arms that bolt to the rails will barely fit between the topper and the side rails and leave no room for the bolt head. I ended up buying bolts that are plain hex head instead of flanged hex head just to make them fit. Adarac might want to use my ideas and develop a product for a similar application. Overall I'm very pleased with the system, it's very high quality.
