Best retractable cover on the market. As a former truck accessory installer, I have installed every brand of cover. Retrax is by far the most efficient design and installation is a breeze. Every other manufacturer has “over-engineered” their covers with too many unnecessary parts and complex adjustment methods.

This is a wonderful product!! I am towing a fifth wheel and this is the only decent option hard tonneau cover that I don't worry about interfering with the trailer. I simply love it and the installation was a breeze! Thank you! My only comment is that you could improve the water drain seal system and provide enough hose and a tee to allow one to plumb to only one side and out.

Could have a little better fit with the 21 Rambox. They don't open all the way freely.
