UnderCover Flex Tonneau Cover Reviews

Reviewed By Jerry W (Mobile, AL) Reviewed for a 2013 GMC Sierra —8/13/2017 5:26 AM

I was amazed that my Undercover Flex arrived sooner than expected. All the parts were there including the instructions. Installation was simple. It looks great on my 2013 GMC Sierra SLT 2500. We've had a lot of heavy rain in the Mobile area and to my surprise the Flex cover kept the bed dry with the exception of a couple of spots which were minor. Thanks for the great service, low price and great product.
