The BAKFlip MX4 was easy to install, and does what I need. I like the new style where I can close my tailgate without having to lift it. 523873

Had it a if a year and this thing takes a beating and it doesn’t have a dent or scratch to show for it. I love it! If your contemplating, don’t! It keeps almost all the water out, except by the tailgate which is normal for any cover. Outstanding product! 663441

Review from a similar BAKFlip MX4 in Tonneau Covers


I am very happy with my BAKFlip MX4 Hard Tonneau Cover - Folding - Aluminum - Matte Finish - BAK48203. Really. And the service I received in its regard was top-notch. It did arrive with a non-functioning blemish but I was compensated by the company, immediately. Also, a part broke shortly after I installed it and again, the company stepped up. As for the tonneau cover itself: •it folds open and closed easily as advertised, •I can stand on it if needed, •it keeps out the rain (I've run it through car washes too, and the contents of the bed remain dry, •it was easy to install •I love that concern for locking the bed by closing before/after tailgate is not an issue. 591725

Review from a similar BAKFlip MX4 in Tonneau Covers


After a year of using the cover I found that there are a few things that could be improved and you can do some of these yourself. The knobs for the cover that actually hold it into the bed-vibrate loose. I added my own lock washers. The poles that you use to hold the cover up when the cover is raised up against the back window-they also vibrate loose-so often that I just removed them and keep them under my seat. The little u-clip pole holders for the poles when not in use-they are too weak-often letting the poles jump out or fall out during normal road driving. The cover itself is not waterproof --it sheds water away mostly however enough gets into the bed that you can not trust your items to be dry. Bag important stuff to keep it dry. The rear weather seal slides back and forth too easily--sometimes working itself out about 2 inches until you see it and slide it back into place--i addenda small amount of silicone to stop this from moving. The cover is strong, looks good and is mostly what I was looking for. Unfortunately I would not buy this again-even more because you have to relocate the bed accessory rails-which then limits the items you can buy for your truck because they are designed for the rails to be in the factory positions. My next cover will be a roll up so that it allows visibility out of the back window. When this cover is flipped up to its final position it completely blocks the rear window. When I was looking at covers-my thought was well its the coolest looking cover and I can deal with not seeing out the back window--well that has changed. It is not practical. The price is high and there are many other options out there that are. My soft roll up tonneau cover was great-waterproof and I could have bought 6 of them for this price. If one was damaged it would have been better to just throw it away and order a replacement. Sorry guys-look elsewhere for a better cover. 739740


Comments
Im sorry to hear about the issues youve had with your BAKFlip MX4. If youre looking to go back to a more traditional style, soft roll-up cover, I recommend checking out the Access TonnoSport # A22050279
Access TonnoSport Soft, Roll-Up Tonneau Cover
$303.58
because it checks a lot of the boxes of things you liked about your previous cover. The TonnoSport is a soft roll up cover that is on the affordable end of the spectrum. It also includes brackets to mount into the OEM rails while they are in their original location.

Love the BAKFlip. Well-built and easy to work. I did notice, however, that I need to be careful with the foam padding that is attached with sticky tape. It does not always hold. As a result, I have to stick it back on. Will have to figure out a way to make them stick better. Otherwise, I love it! 916553

I am a huge fan of the BAKFlip. The installation was pretty straight forward and easy. Anybody with moderate mechanical ability can install. I think it took less than 2 hours. I live in a heavy snow area and had more than 24” of snow on it at one point and the product performed flawlessly. 914709

Review from a similar BAKFlip MX4 in Tonneau Covers


I had a some trouble putting it on since I had a bed liner on my 2017 Ford F-150. It did have a long scratch on the black paint which is not seen unless I flip it up against the back of the truck cab. Overall the construction quality is very good and it looks like it should last five to eight years under my type of moderate use. 902718

So after a year I am still loving this bed cover. Had the fiberglass version for my 2013 F-150 and loved it as well, that's why I purchased this one for my 2019 Super Duty, it was also the first accessory I purchased for it because I was so used to my other one and knew I couldn't live without it. I never installed the drain tubes on either covers and still haven't had water get it my bed. Also the folks at etrailer are always awesome! Thanks again! 893408

  • Compatible Ladder Rack and Tonneau Cover for 2018 Ford F-350 Super Duty Long-Bed
    Often tonneau covers and ladder racks interfere with each other when they require common mounting points on the truck bed rails. But there is a compatible combination that we know from experience will work well on your long-bed F-350. BAK Revolver Series tonneau covers # BAK79331 and # BAK39331 mount inside the bed rails which allows use of the TracRac SR sliding ladder rack which mount on top of the bed rails. Several versions of the SR are shown on the linked page. For your long-bed...

  • Will BAKBox 2 Work with RetraxPRO MX Tonneau Cover for 2017 Ford F-350 Long Bed
    The BAKBox 2 Collapsible Truck Bed Toolbox # BAKBX92333 is designed to work with rails on the BAK Revolver X2/X4, Roll-X (discontinued), and BAKFlip tonneau covers. Although the BAKBox 2 has not been tested for compatibility with the RetraxPRO MX Hard Tonneau Cover for your 2017 Ford F-350 long bed, part # RT80384, from what I can see, it's highly unlikely that they would work together. Below are the correct part numbers for the available tonneau cover options that do work with the...

  • What Ladder Rack will Work with the BAKFlip MX4 Hard Tonneau Cover on a 2018 Ford F-350
    I do have options for you but the Thule TracRac SR Sliding Truck Bed Ladder Rack part # TH43003XT-000 won't work with the BAKFlip MX4 Hard Tonneau Cover part # BAK48331 on your 2018 Ford F-350. The reason for this is because the uprights on the ladder rack are angled inward and the folding slats on the MX4 would come into contact with the uprights when lifted. You may be able to open the first slat if you moved the rear upright all of the way forward but this is surely not ideal. Instead,...

  • What Ladder Rack Will Work with the BAKFlip MX4 Tonneau Cover on a 2020 Ford F-350 Super Duty
    We do have a ladder rack solution for your 2020 Ford F-350 Super Duty with the BAKFlip MX4, part # BAK48330 for short bed or # BAK48331 for long bed, but you are correct that the vast majority out there use a clamping system which makes them incompatible with most tonneau covers. For your application you can use the Adarac Pro Series Ladder Rack, part # A4000952 for short bed or # A4000958 for long bed, because it uses an anchoring system with the stake pockets instead of a clamping...

  • Could BakFlip Tonneau Cover Close Over B and W Companion Fifth Wheel Hitch in 2019 Ford F-250
    We do install fifth wheel hitches and rail kits here at our location in Wentzville, MO and it is possible a BakFlip Tonneau can fit over a fifth wheel hitch but the hitch would need to have a handle that does not point up like the B and W Companion part # BWRVK3500. To install this in your 2019 Ford F-250 long bed you'd need the rail kit part # BWGNRK1116. I attached an install video for this for you to check out as well. In case you didn't have the tonneau already the correct part...

  • Stake Pocket Compatible Ladder Racks for 2019 F-350 With Tonneau
    The Thule TracRac Contractor Truck Bed Ladder Rack - Side Mount - Steel - 250 lbs # TH14750 gets the support it needs from the floor which is why there isn't a similar rack compatible with stake pocket use. You can get a full ladder rack that will use the stake pocket and utilize the full side to side bracing for support like the Adarac # A70450. IF you let me know your specific vehicle, I can give you a compatible rack option. To not interfere with a folding cover you would need to...

  • Will Extang EnCore Fit with 5th Wheel Trailer on a 2018 Ford F-350 Long Bed
    You should be able to install a 5th wheel hitch and couple up to your 5th wheel trailer with the Extang EnCore Hard Tonneau Cover # EX62430 installed and in the folded up position on your 2018 Ford F-350 Super Duty but it will definitely reduce your turning clearance. I have some similar recommendations for you though. I recommend going with the BAK Revolver X4 Hard Tonneau Cover # BAK79331 instead. This combines the sleek look of a soft tonneau with the durability of a hard tonneau...
