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.

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 on 25 Sierra 1500

The BakFlip is a premium quality cover. I had one on a 19 Frontier and it was great. About 98% dry. I put a Gator folding cover on a 25 GMC Sierra 1500. That truck got totalled at 903 miles. I installed the Bakflip on my replacement 25 GMC Sierra 1500 last week. I prefer the matte finish on the BakFlip compared to the shiny satin finish on the Gator. Both covers required a little "tweaking" to get the latches to catch just right, The Gator design preferred that I close the tailgate with the top open. The BakFlip design works well both ways. That is I can close the tailgate with the cover open or closed. The BakFlip permits the whole folded cover to be flipped up to lean against the truck cab. This is necessary when hauling items like a motorcycle for example. In contrast the Gator cover must be removed since it does not flip up against the cab. In the past 3 months I have purchased both folding tonneau covers and installed them on identical 25 GMC 1500 Sierra pickups. While the BakFlip cost nearly twice as much, I would pay the greater amount again to have the advantages the BakFlip offers over the Gator and the Matte finish compliments my trucks trim better the the shiny satin Gator finish. For budget conscious folks the Gator is a good quality option that frankly is a better bang for the buck buy than the BakFlip. But it all comes down to preferences. The Gator was about 95% water tight. I cannot comment on the BakFlip since I've seen no rain since installation.
