I have the American Tonneau Tri-fold. I got it from Summit Racing for about $250. I think the $800 covers mentioned above look awesome and I'm sure they are better in some way but I couldnt justify the expense to myself...Im a cheap ass and a cover was not a high priority for me mod wise. Although, I think $800 for a cover on a 40k+ truck is reasonalble. All I needed was something to keep water and snow out of my bed and keep small loads from flying out on the highway. I don't keep any valuables in the bed so the vinyl cover provides all the security I need. The cover was extremely easy to install just set it on the bed tighten two clamps, unfold it, then flip two levers to lock it down. The portion closest to the cab does not fold up but you can take the whole thing off in like 2 min. Overall quality seems OK, its made in the USA so thats a plus... I might eventually upgrade to one of the covers metinoned above purely for the astetics, they look very sleek!
