Top Positive Review

I originally bought this cover in Nov 2018 for my then-new F150. Quality was as expected from past experience with this company. Sharp edges at the ends of the rails, packaging full of aluminum shavings, cheap foam bumpers not up to par, just not finished very well considering the $900 price tag. But it was well packed, looks good, works great, and I love it.

Now for my most recent purchase:
I bought another one last month for my dad’s 2019 f150. Huge difference. All of the sharp edges are now covered, new textured paint on the side rails, plastic caps over the rail ends. Corners of the cover are finished with nice square trim pieces, the foam bumpers are upgraded to actual rubber that looks like it should last. The cheesy little plastic loops that hold the prop rods have been replaced with actual clips. Also, the packaging was completely free of all the chips and trash that I had to clean off of my cover last year. They have really done a nice job and it feels like a more expensive product. I was impressed and jealous at the same time.

The price was steep, even with a $100 rebate but I’d buy another one without hesitation. It’s good to see any company take feedback and invest in the product rather than sit back collecting cash until competitors do it right and take the business away from them.

Update 28 months later:
Foam pieces that separate panels during folding are torn and falling off. Scratches all over the panels. From what, washing with a microfiber mitt??? I got my weakling electric pressure washer too close while rinsing soap and it blasted a bunch of paint off. The matte black looks nice but it is not even as durable as the lower priced G2. Knocking off a star for durability.

Top Critical Review

I installed the MX4 on my new 2018 Ford F150 yesterday. I did a lot of online research before selecting this tonneau cover. I ignored some of the negative comments on the MX4 as one offs, but unfortunately that was not the case. The side rails were heavily scratched even though the packaging was intact and the rails were in individual plastic bags that showed no wear. This is totally a quality control issue as rails are getting scratched in the manufacturing process and BAK allows them to be packaged and shipped. The top of one of the panels also has a long scratch on it as well. The overall design is good and the installation was also pretty easy. It hasn’t rained yet so I can’t comment on how well it seals the bed. I suspect not that well given that the rubber seal along the top buckles at every seam. Overall, I wish that I had heeded some of the negative comments on the MX4 and selected another manufacturer. Haven’t decided whether I will return it or not. My advice would be to avoid BAK until they improve their quality control.

Customer Questions & Answers

Can you drive with one section open i.e. if you were hauling boards that needed to stick out the end.
Answer: No, this needs to be secured in one of three positions. Full closed covering the entire bed, folded all the way up and buckled covering the first 1/4-1/3 of the bed, or fold and buckled up against the cab window.

Does it lock?
Answer: None of our covers will have a lock built into them. However, as long as you have a locking tailgate the latches are inside the bed and will be secure.

How much of the bed does this take up in the fully folded (against the window) position?
Answer: Depending on the position of the, when folded up against the window the top will take up 6-8′ of the bed.

When folded up against the truck cab as noted, does rub against the cab or window, potentially scratching it?
Answer: They provide rubber bumpers to mount on the cover so protect the back of the cab. I have had this for a year and so far no issues. Though I do not drive a ton with the cover folded up.
