Ok here is what i have ran into. The Bak Industries reviews on their website says for the Hard Rolling covers that in cold weather like 30 degrees and below that the vinyl pulls away from the aluminum with not much help from BAK. Then there is Truxedo Titanium Hard Rolling that has really good reviews and even for use in cold weather. Now has anyone had any experience with the Hard Rolling Cover from GM Accessories made by REV. So who is REV? Nothing comes up on Google or Youtube that I could find review wise. A dealer offered me a pretty good price installed but I don't want to buy again after a couple years. Need to do it once and be done. Anyone got anything on the REV Brand or know who the REV brand is?
