UnderCover Flex is GREAT!
The tonneau arrived before expected. It was extremely easy to install. I completed the installation myself in less than an hour. I have not yet been through a rain storm, but I have been through the car wash a couple times, and with the exception of a couple wet spots up by the bulkhead, the interior bed was completely dry! This was an EXCELLENT choice and I would recommend to friends and buy again.
HardFold Tri Fold Cover Review
For the price, this is an excellent product. Time will tell how well it holds up to the extreme weather conditions of south Texas. The only negative I encountered was the poorly written installation instructions. I had to call the Customer Service department for assistance. Staff were most friendly and with their help I was able to install the cover easily.
