Overall, very good buy!" —Josh T from Sahuarita, AZ bought a BAK BAKFlip G2 Tonneau Cover for a 2011 GMC Sierra.
"Installed 2 weeks ago. I need to add weather stripping to get it to seal better. The cover flutters alot over 70mph. The pivot areas dont look the best when it is folded out flat on the bed. It doesn't seem to be a bad cover for the price." —Rick H from Oakland, IA bought a TonnoPro TonnoFold Tri-Fold Tonneau Cover for a 2011 GMC Sierra.
"Like the cover and ease of installation. Great value and looks pretty good. My only complaint is the rear corners are raised up a bit in order to clear tailgate opening and closing." —Steve K from Highland , MI bought a TonnoPro TonnoFold Tri-Fold Tonneau Cover 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.
"Talked to another individual who had the Extang Trifecta Folding Tonneau Cover on his vehicle and he actually showed me how it worksd right there in the parking lot. I really like the cover, especially since the tail gate locks. Simple to install. Just as the instruction stated, it took longer to get it out of the box then to put it on the truck." —Charles G from Oakdale, PA bought an Extang Trifecta Folding Tonneau Cover for a 2011 GMC Sierra.
"I took my time and looked at several Tonneau Covers locally and on the internet before I decided to purchase the TonnoPro Tri-Fold Cover. The TonnoPro seems to be well built and made of quality materials. The cover installed in minutes and fit well.
I am very pleased with my purchase and would reccomend this cover to others.
I had one slight problem, when clamping down the latches near the tailgate to secure the cover, I noticed that the hard plastic latch slide was being pinched between the cover frame and the top of the bed, not allowing the cover to become tighlty secured. Over time, if this problem was not corrected I'm sure that this would have scratched the paint on the truck bed. I called TonnoPro customer service and they sent me (that day) two new plastic clamp latches that were about 1/2" longer than the original parts that came with the cover and this solved the problem. TonnoPro Customer Service gets 5 Stars as does Autoanything.com for the smooth sales transaction." —John T from Pittsburgh, PA bought a TonnoPro TonnoFold Tri-Fold Tonneau Cover for a 2011 GMC Sierra.
