I got this when I got the truck but upgraded to a camper shell. It is "undercover" brand and I have all of the parts and keys. Really strong lid. Only fits the short bed on the Crew cab model from 07 to current. $450 or maybe a trade for something. 10/22 or maybe a 22 pistol of some flavor or something. Here is some info on them. http://www.undercovertonneaucovers.com/GMC-Undercover-Tonneau-Cover-p/ucc-sierra.htm
