We've had consistent solid service from Access covers. We've had them on five trucks - Tundra, GMC, and Chevy - starting over 20 years ago. We currently are trying a cap on for winter, but I don't love it. I expect we'll pull the cap and reinstall our Access cover and Adarac M-series, which lets us have a rack over the bed and still have the roll-up cover. When we want to haul tall stuff, we can remove the rear rack in minutes, or just loosen the 4 bolts and slide it forward.
I wish Access would come up with a rack that we could put a temporary cover on -- so we could protect large stuff in bad weather -- and then go back to the bare rack and roll-up cover. Until that comes out, we'll stick with the current Access + Adarac setup.
