I had a BakFlip on my 2018 Ford F-150 and really loved it. So after trading in my F-150 for my new F-250 I wanted the same cover on it.

As advised, I also purchased the Bed Rug. It's luxurious for my wife's truck, but, keeps everything loaded very clean and easy to unload. Thanks for all you did for my purchase to make my wife happy!!

Great product. Very well built. I have a fifth wheel hitch in my bed and the BAKflip does not interfear with it at all. Now i can finally transport items in my bed that i don’t have to worry about. I would HIGHLY recommend this product to anyone with a pickup truck.
