"I purchased the cover for my 11 Sierra and it fits great ,opens great and looks fantastic. Auto anything price matches and i saved 46 bucks on it..." —James T from Ocean Springs, MS bought an Extang Trifecta Folding Tonneau Cover for a 2011 GMC Sierra, Standard bed (approx. 6 1/2 ft.), without Cargo Management System.
"I read the many positive reviews for this product on-line and just hoped they were true. They were! I searched many options for a cover to my 2009 Sierra short-bed. I felt the Lund Tri-Fold Tonneau Cover was the best product with the features I wanted at a decent price. I could not be happier. It arrived in three days and my wife and I had it on and adjusted in about 5 minutes. The snap clamps are ingenious and work great. And, the cover looks great. I could not be happier." —Robert D from Painesville, OH bought a Lund Genesis Tri-Fold Tonneau Cover for a 2011 GMC Sierra.
"The Tonno Pro cover is a easy installed cover like the video described and they even give you 2 replacement plastic clips for mounting in case any would break, the only problem with the cover I noticed is after mounting no matter how tight you tighten the clamps the four corners seem to liftup a little so it dosent look completley flat, they should have mounted the clamps more toward the end of the tonneau instead of more toward the center, it needs more mounting pressure toward each corner to hold it firmly down on the corners,it should have six clamps really and that would solve the problem, but overall its a decent buy for the money." —Richard L from Jacksonville, FL bought a TonnoPro TonnoFold Tri-Fold Tonneau Cover for a 2011 GMC Sierra, 6' 6" short bed, without utility track system.
"Easy to install, took two people less than 5 minutes. Would be nice if it had a way to lock and secure it once on the truck. Without a tailgate lock anyone could unscrew the latches and steal it less than 2 minutes. Consider buying a tailgate lock if yours does not lock." —Chris W from Hiram, GA bought an Extang Trifecta Folding Tonneau Cover for a 2011 GMC Sierra.
"I am very pleased with the purchase of my Bakflip G2. It was easy to install and has lived up to my expectations. Also, my fuel MPG has improved by 1/10th since installing bed cover. It does not sound like much but, it's an improvement." —Steve N from Jonesboro, AR bought a BAK BAKFlip G2 Tonneau Cover for a 2011 GMC Sierra, Crew cab, 5' 8" short bed, without Cargo Management System (CMS).
"Just moved from a Silverado with a 6.6' bed to a 5.8' bed so was unable to move my "other brand" tri-fold - this cover was at least 25% less than that brand so I decided to give it a try - I actually like it better - great quality, fit and ease of installation - these tri-folds actually install in 10 minutes or less - great cover! Great service from AutoAnything too - this is my new source for accessories!" —Dennis B from Swartz Creek, MI bought a TonnoPro TonnoFold Tri-Fold Tonneau Cover for a 2011 GMC Sierra, 5' 6" short bed, without utility track system.
"I installed my Bakflip and toolbox by myself in a short asmount of time. My only problem was having to decide which one actually went in first. Just to be difficult I put the bakflip on first and then put in the tool box. It made for a tight fit but I didn't have any problems. I would recommmend that the directions tell you to but the box in after the side rails and right next to the extended holders on the lid." —Rus B from Amarillo, TX bought a BAK BAKFlip G2 Tonneau Cover with BAKBox Toolbox for a 2011 GMC Sierra.
"Easy to put on or take off. Corners seem to be "up" a bit. Very well worth the cost." —Fred F from Erin, NY bought a TonnoPro TonnoFold Tri-Fold Tonneau Cover for a 2011 GMC Sierra, 5' 6" short bed, without utility track system.
