I fought with the idea of putting a fiberglass cover on my truck for a long time. I finally decided to go with the "roll and lock" brand. This is an aluminum cover that retracts into a container mounted below the rear window. It payed for itself the first weekend I had it. It looks sharp, mounts to the bed without drilling, provides a lockable / water esistant storage area and gives you full acces to the truck bed if needed (I tow a fifth wheel). I have had so many compliments on this cover. The price was 1,100.00 intalled.
