"When I first saw the display of the Extang Folding Tonneau Cover. I thought this is the one I want. No snaps, no velcro, no support bars to mess with, and no brackets to clamp down. Now that I have it I realize it is even better than I thought it would be. I show it off to all my friends.

"I got the TonnoPro tri-fold for my GMC 1500 Sierra with an 8 foot bed. The installation was simple and after having it on for a while, I've had no problem with leakage. It certainly makes useful space of the bed for when we go to camp." —Charles S from Woolwich, ME bought a TonnoPro TonnoFold Tri-Fold Tonneau Cover for a 2005 GMC Sierra.

"Measured on the 270 mile run between Nashville and Cincinnati, my '05 1/2 ton Sierra with the aluminnum block V8 would average 18mpg at 75mph. After BAKflip was installed, it got exactly 19.5mpg at the same average speed. On the return trip, I averaged 85mph, which was typically 16.5mpg - the truck now got 18.3mpg. Save to say that BAKflip will improve fuel consumption by 8%-12%.The BAKflip is decently made, seems sturdy enough. Installation instructions are poorly detailed but the product can be easily figured out. The drain tubes were too large for the bed drain holes but that was fixed with 1 foot of next-size-smaller tubing, 2 hose clamps, adhesive chaulk and black electrical tape. An annoying detour that cost less than $5.The BAK flip looks good and it looks even better if combined with tube style bed rails." —Lee K from Nashville, TN bought a BAK BAKFlip G2 Tonneau Cover for a 2005 GMC Sierra.
"I own a body shop and had to get cover for a customer. installation was easier than I was expecting, the whole cover was installed in less than an hour, and looked great. customer liked the bakflip better than the cover he had before. thanks jason" —Jason W from Springfield, MO bought a BAK BAKFlip G2 Tonneau Cover for a 2005 GMC Sierra.
"Works great, looks great..." —Robert R from Lapeer, MI bought a Lund Genesis Tri-Fold Tonneau Cover for a 2005 GMC Sierra.
"I was really impressed on the quality and ease of installing. Highly recommend this product." —Arthur W from Brookfield, NY bought an Extang Trifecta Folding Tonneau Cover for a 2005 GMC Sierra.
"Cover seems to do exactly what I wanted. Looks good, fits well, keeps water out. Though I haven't checked gas mileage since it's been on, I have noticed that my truck tends to pick up more speed coming down a long slope than before, as there is now less wind resistance, so it stands to reason that fuel economy would be improved a bit. I have it installed on an 05 Sierra Crew Cab, and with a family of five, it's nice to have enclosed, water-tight storage space in the back (think large trunk). Very easy to undo and fold back for hauling taller items or gaining access to front of bed. I wish it were theft-proof, but I didn't want to pay double (or more) for a hard cover. Time will tell how well it holds up, but it seems durable. Really improved the overall looks of the truck. Highly recommended." —John C from Arab, AL bought a Lund Genesis Tri-Fold Tonneau Cover for a 2005 GMC Sierra.
"After I placed my order, I received my Extang Trifecta Folding Tonneau Cover in about 3 days, half the time predicted... It litterally took me 5 mins. to take it out of the box and install it on my truck... And it looks GREAT too!!! I'm very pleased with my purchase from AutoAnything.com" —Stephen Y from Newport News, VA bought an Extang Trifecta Folding Tonneau Cover for a 2005 GMC Sierra.
