"Economical, easy to install, and best of all it looks and performs great. I highly recommend this tonneau cover." —Steve L from Buffalo, NY bought an Extang Trifecta Folding Tonneau Cover for a 2008 GMC Sierra.
"The Bakflip is a good choice if you need to be able to fold up your hard tonneau cover. On another truck I have the Undercover hard tonneau and it is great but is not as convenient as the Bakflip. The Bakflip works for me on this truck better because I tow a gooseneck trailer." —Matthew E from Harrisonburg, VA bought a BAK BAKFlip G2 Tonneau Cover for a 2008 GMC Sierra.
"I read up on a bunch of covers and felt this one was perfect for me. It came as represented in catalog and also installed as easy as all the reviews said it would. Very satisfied and have had several snow storms since installing it 2 weeks ago." —John E from Flanders, NJ bought a TonnoPro TonnoFold Tri-Fold Tonneau Cover for a 2008 GMC Sierra.
"Excellent product for value, very easy to install, and looks great. Arrived in very short time." —Frederick S from Saint Ignace, MI bought an Extang Trifecta Folding Tonneau Cover for a 2008 GMC Sierra.
"The Trifecta cover is a terrific product! It has exceeded all my expectations in looks and functionality. The cover is a snap to install/remove (one man-3 minutes) and looks like an expensive convertible top. There are no adjustments required, no measuring and the spring loaded attaching clamps are a perfect fit right out of the box. I was concerned about water intrusion on my first trip since there was no time to install the tailgate seal before departure. Sure enough, we hit a fierce rainstorm on the way home from the Gulf Coast, but...... there was literally no water leakage into my GMC Sierra Denali pickup after two hours of driving rain. The top rail fit is tight all around and the cover is so easy to fold and unfold by one person. So label me a very happy customer with my new cover and with the AutoAnything order process." —William L from Brownsboro, AL bought an Extang Trifecta Folding Tonneau Cover for a 2008 GMC Sierra.
"I was a little hesitant to buy this cover because of the price.However the concept of a tri fold is what made me decide on this cover. The cover took me about ten minutes to install with no tolls. It is so easy to operate you can fold it and unfold it in seconds. I have owend this cover for several months and have been through several heavy rain storms and the cover never leaked. This cover is worth every penny I spent for it." —Michael S from Trenton, NJ bought an Extang Trifecta Folding Tonneau Cover for a 2008 GMC Sierra.
"The installation was a snap.Only needed a wrench for the side rails, no cutting.My truck bed was sprayed with rhino liner that went up over the side rails which did not effect the fit.I used the long spacers on each side rail along with the 6 shims for each clamp.The only thing i did not use were the two hoses for drainage they were short and to big.I replaced the hose with 3/8 hose which fit inside the nipples and ran them down to the floor of the bed through holes i drilled, much better than they suggested.when sliding the hose inside the nipples only go about an inch and coat with a clear silicone before doing so, so they stay tight." —Michael C from Alden, NY bought a BAK BAKFlip G2 Tonneau Cover for a 2008 GMC Sierra.
"Very easy to install. Looks great and works well.
went to a car wash and was high and dry." —Jeffrey P from Wesley Chapel, FL bought a TonnoPro TonnoFold Tri-Fold Tonneau Cover for a 2008 GMC Sierra.
