I just bought the tow vehcle, 07 Chevy 2500 Crew Cab Short Bed, ready to install the 5th Wheel hitch, Reese 16K w/slider. Does anyone have experience with bed covers? I was thinking of installing a bed cover for when we are not towing and when we are camping but going to town w/o the 5th wheel attached. Can we use a retractable cover or is a roll-up tonneau the only option?
