Has anyone installed a Peragon bed cover on the truck? Also how about the RETRAX bed cover?

 

there's several people on here who have had the Peragon...I'm planning on getting one of those soon, as my vinyl Extang is such a hassle that I just leave it off most of the time

plus I dig that you can lock it...I want to combine it with the Pace Edwards tailgate lock that works with your power door locks
