BAK BAKFlip G2 Tonneau Cover Reviews


Very nice cover for a reasonable price.

Reviewed By Kenneth E (Freeville, NY) Reviewed for a 2013 GMC Sierra —4/25/2017 9:00 AM

The BakFlip G2 is a very nice looking tonneau cover and installs quite easily. Took me about 2 hours doing it alone, had a significant rain storm the next day and for the most part remained dry. There were a couple small pools of water on each side near the tailgate. May look into trying to remedy that as it gets warmer but is not enough water to hurt anything I may keep in the truck.

Great product !!!

Reviewed By Bedford G (Cordova, TN) Reviewed for a 2013 GMC Sierra —2/25/2017 9:14 AM

Great service, quality product, and most of all a great price. Received the order from Auto Anything and read the install directions. I found everything very simple and easy to install. Took maybe a hour. I have revived several compliments on the appearance of the cover. I think this is one of the best covers on the market. Highly recommended!!!

TonnoPro TonnoFold Tri-Fold Tonneau Cover Reviews


Great buy

Reviewed By Marc M (Pittsburgh, PA) Reviewed for a 2013 GMC Sierra —12/14/2016 12:14 PM

I bought the TonnoPro after reading other people's reviews and made the right choice. Easy installation, on/off, and fit well. The only negative thing I can say so far, is the sides of the cover don't look flat because of the Tri fold hinges. I do recommend this product.
