2016 RAM 1500 bed cover

I went from a ARE fiberglass lid to this. . . Which limits you extremely. . The MX4 cover looks really good. . . . Easy install. . locks with tailgate. . Was missing one screw for the buckle latch, no biggie. . . never throw out extra hardware from any install!! Overall happy with product

Well done!

This is my second Bakflip tonneau cover. The first was purchased in 2016 and is still working perfectly. This MX4 is a newer generation that brings in many improvements such as aluminum panel that are stronger, better latches and cable runs, the straps to secure the panels when partially open and my favorite improvement is the ability to open and close the tailgate with the tonneau fully closed. In addition to these improvements the rail and mounting system made my installation a breeze! Well worth the cost.

BAKFlip MX4 Cover is AWESOME!

I needed a new cover for my new Denali pickup. I shopped many other brands and watched many videos on other covers. I decided to buy the the BAKFlip MX4 cover. I watch videos on how to install it and it installed pretty easy. Took me about an hour and a half because I am so particular. I love the way the cover looks. I also like how it folds. It locks down each section. You can also fold it up against the window to give you all the bedspace. I am very happy with my purchase.
