This cover looks amazing on my F-150 and works even better. I can open it up fully when I need to haul stuff, and it keeps everything dry and secure. Install was super easy.

I’ve had this Flex cover on my truck for six months and it’s held up great. It folds up easily, looks sharp, and gives me full access when I need it. Definitely worth it.
