I've got one I would sell you. New in box never installed. It is designed so the brackets go under the camper shell and the rack can be removed from the brackets without removing the shell. The pics you refered to look like a cargo or safarri rack. The one I have is more like a true ladder rack. Send me a pm if you're interested and I can take pics of it for you. I have no pics of it mounted to my truck but I can show you were to get pics of it installed, and I take pics of the one I have.
