"Had a roll in hard cover which took up too much of the box. Also allowed water into the box. Received new tonneau quickly and easy five minute install. Drove fron Florida to Canada. It rained heavily for 7-8 hours. I had cardboard boxes in back and they were totally dry. Very pleased." —Peter F from Leesburg, FL bought an Extang Trifecta Folding Tonneau Cover for a 2003 GMC Sierra.
"I purchased the TonnoPro cover after having the factory hard cover removed. This cover was so easy to install, you would have to be missing a chromosone to mess it up! Put it on and drove 2,200 miles to Buffalo NY and back; through the wind, snow, rain, and my led foot, NO PROBLEMS!!!! On occasion I would check the clamps and again no problem. It looks good on the truck and I'm sure with proper care and attention will last a long time. If not I will buy another one!" —Teresa O from Joplin, MO bought a TonnoPro TonnoFold Tri-Fold Tonneau Cover for a 2003 GMC Sierra.
"Love the product, Price a bit high, but you get what you pay for. The shipping container leaves a lot to be desired. The box needs more padding,so there are not slight scratches and imperfections from shipping. Easy to fix scratches but for the price you would think they would wrap it better." —Arlin K from Radcliff, KY bought an Extang Solid Fold Tonneau Cover for a 2003 GMC Sierra.
