"About 8 months ago I ordered a TonnoPro Tri-Fold Tonneau cover for my 03 Dodge Ram and I liked it so much 2 weeks ago I ordered one for my 04 GMC. Out of the box it only takes about 3 mins to install. Works great and looks great. You cant beat the price. If your looking for a tonneau this is a great one. If you need to use the bed for big stuff you can fold it up and clamp it down or take if off and put in bed, when done put it right back on.
