Solid performance. Only issue is with the glue holding the pads is failing


Comments
You mentioned that the glue holding the pads are failing. I wanted to see if you would be able to send a picture to show the locations.

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!




by:

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.

Excellent tonneau, easy install, quality product. Installed a year ago, no problems, still looks like new




by:
2017 Ford F-250 Super Duty

It's a straight forward assembly but photos of the assembly steps would be better than the illustrations.
NOTE: This model allows you to open and close the tailgate without lifting up the cover. The other models require you to lift the cover so the tailgate won't damage it.

Great cover holds up really well, no problems

2017 Ford F-350 Super Duty

After a year with my BAKFlip MX4 tonneau cover, I'm completely satisfied, in my opinion, that I purchased the best rigid and secure cover for my 2017 F350 Super Duty truck, with 6'-9" box.

Keeps out the water well. However if you do a lot of dirt roads like I do a lot of dust still gets in. No regrets buying it.

Great product, a little pricey but you get what you pay for. It keeps objects save and protected from the weather. Very well built and have had no issues.

Review from a similar BAKFlip MX4 Tonneau Cover in Tonneau Covers


Overall, I am very pleased with my BAKFlip MX4. It has held up well after 1 year. It works well and looks good. It matches my matte black accessories and trim. It was fairly easy to assemble but I did have some tight fitment issues near the cab where the cover connects to the rail. I really like the security of the hardtop and access through the tailgate. Water is generally kept out, but sometimes there are water drips near the tailgate depending on the angle parked. So this cover keeps the bed *mostly* dry.
etrailer was very fast to deliver my cover, and it came in good condition.

Review from a similar BAKFlip MX4 Tonneau Cover in Tonneau Covers


I love the cover, very sturdy and has held up very nice for 1 year. The one issue is, I have a long bed Ram and when I fold it up against the cab, it covers the camera for the bed. This is a design flaw and if you use the bed camera when you have a load in the bed and the cover is folded all the way up, you can't use it.

Review from a similar BAKFlip MX4 Tonneau Cover in Tonneau Covers


All is well....except, the caps at the joints of the folds keep popping out of place. leaving unsightly bludges in the top. With some work you can pop them back in place, sometimes easily sometimes not. Overall pleased, this is our 2nd BAKFlip and would purchase again.


Comments
I have gotten in contact with one of our installers and they suggested that if those components are popping out, they should be able to be glued in place.

Review from a similar BAKFlip MX4 Tonneau Cover in Tonneau Covers


It was very easy to install even though I had never installed a tonneau cover before. One year later, the finish is still excellent. I never installed the drain tubes to divert any water from the outside but very little water ever infiltrates past the cover even when I wash the cover with my hose. One minor thing that can be an issue is when unlatching and latching the middle of the five panels, the end cap on the hinge near the bedrails sometimes disengages. The cover still closes if I didn't notice the disengagement but I'll just flip back and tuck the end cap back in to the hinge, no big deal. Overall very sturdy and durable. My neighbor wants one now.

Review from a similar BAKFlip MX4 Tonneau Cover in Tonneau Covers


Easy to install, and it holds up pretty well. The straps that hold it down when partially open can get in the way and one clip got broke. You have to be careful when loading big things with the top down that you don’t snag the straps, clips or cables. The prop rods are good but can get beat up by the loading process too. Also the knobs for the prop rod keeepers can fall off in the bed when the cover is closed. You need to make sure they are tight. Over all a great product, I love that it is strong, flat and solid and makes the whole bed secure. Also handy to set things on when working around mid the truck or for carrying stuff.

Review from a similar BAKFlip MX4 Tonneau Cover in Tonneau Covers


I have owned this cover for over a year and it has been excellent. It keeps the bed fairly dry as expected and I have had no mechanical issues with it as it still performs like new. I would say the only improvement I would suggest is better foam weather striping for the front of the bed as the original never stuck to the spray in liner very well and eventually came lose and then I just swapped with some similar weather striping I bought locally.

Review from a similar BAKFlip MX4 Tonneau Cover in Tonneau Covers


Installation was easy, although it has never aligned perfectly. It has worked well, although it has been designed to be usable in the open position with the last panel (closest to cab) closed and the folded portion strapped into position. I bought it specifically for that so I could access my 5th hitch and tow, with a portion covered. It seems to be stressful on the cover to use it this way…all of the foam bumpers have worn off and have even put some dents in the cover. It’s a great concept, but could use some design tweaking.

Review from a similar BAKFlip MX4 Tonneau Cover in Tonneau Covers


I like the tonneau cover a lot! It's sturdy and helps keep belongings out of sight, out of mind. I had to cut the rail as it was about an inch too long for my truck but besides that the install was easy.


Comments
I reached out to the manufacturer and they said if you install the rails with the tailgate closed then the rails would sit on top of the tailgate, which is correct.

Review from a similar BAKFlip MX4 Tonneau Cover in Tonneau Covers


This is the third MX4 that I have owned. This one is on Ford’s Maverick. The first two fit well but not perfect. I don’t really know if the slight issues were the fault of the truck or the cover. This cover is the best yet. Absolutely no leaks!! The fit to the tailgate is very uniform!! When ever I need a cover, I don’t even look at te competition. These are great covers.

  • How Waterproof is BakFlip MX4 Tonneau Cover for 2020 Ford Super Duty 6-3/4 ft Bed
    The BakFlip tonneau cover part # BAK48330 that you referenced will do a great job keeping most of the water out of your truck bed, but it's not totally waterproof so there's a possibility water will still get in during a heavy downpour. It has a drain system too that helps direct the water out of the truck as well.

  • What Is The Dimension Of The BackFlip MX4 When Folded Up On A 2017 F-250 6-3/4 Foot Bed?
    The BAKFlip MX4 Hard Tonneau Cover - Folding - Aluminum - Matte Finish, # BAK48330, is a quad-fold cover. I reached out to my contact at BAK industries and for your 2017 Ford F-250 Super Duty with 6-3/4 foot bed, the depth of all the folds together is 3-4 inches. Each panel is 1/2 inch thick but there are also the support rails. They were unable to give me the dimension exactly for this specific cover when resting on the panel closest to the cab, but that would remove a 1/2 inch. ...

    Hey Robert, so we have a BakFlip tonneau that does fit your 2006 Ford F-350 long bed with the part # BAK26304 but the part # BAK48330 that you referenced fits short bed Ford trucks that are much newer than yours so this won't fit at all.

    Thank you for all of the info! You do bring up some excellent points and while I wish I could tell you that the BAKFlip MX4 # BAK48330 will work, you are correct that you'd have clearance issues so you'll be better off with a different cover.

  • Comparing BAK Tonneau Covers MX4 and G2 for 2017 Ford F-250
    For your 2017 Ford F-250 the Bak MX4 part # BAK48330 and the BAKFlip G2 # BAK26330 are both pretty similar in that they are folding aluminum tonneau covers that will fit and work great, but there are a few differences. The biggest being that the G2 has three sections that fold and the MX4 has 4. The MX4 is also compatible with the BakBox which is a storage box, part # BAK92100. The MX4 also has a weight rating of 400 lbs evenly distributed on it while the G2 isn't rated at all.

  • Best Ladder Rack for 2019 Ford F-250 Short Bed with BAKFlip MX4 Hard Tonneau Cover Installed
    Yes, the Adarac Pro Series Custom Truck Bed Ladder Rack part # A4000952 will work on a 2019 Ford F-250 with BAKFlip MX4 Hard Tonneau Cover part # BAK48330. In fact, the Adarac Pro Series is actually the only ladder rack that will work with the BAKFlip MX4. The reason for this is because the uprights on the Adarac Pro Series are straight so they will not interfere with the panels on the BAKFlip MX4. Unfortunately, the Adarac Pro Series is not offered in black but you could paint this yourself...

  • Recommended Tonneau Cover for 5th Wheel Towing with 2022 Ford F-350 Short Bed
    According to BAKflip, when the # BAK48330 is folded up against the rear of the truck cab, it'll reach into the bed by about 9 inches. Since the cover sits against the back of the cab when folded up and reaches most of the way up to the roof, it would be a little too close for comfort to the front corners of your 5th wheel during turns. I'd rather see you use a retractable cover like the Retrax # RT60383 which will not extend up past the top of the bed sides when fully retracted, so it...

    The best tonneau cover for a 2019 Ford F-350 is the BAKFlip MX4 Hard Tonneau Cover part # BAK48330. I prefer the BAKFlip MX4 because it has a hard top which means your contents inside the truck bed are truly safe, it has a low profile design so you don't have to worry it sticking up from the bedsides taking away from the look of the vehicle, and it is very durable therefore you don't have to worry about it getting damaged when using your truck as a truck.

    You would be able to install the TracRac SR Ladder Rack part # TH43002XT-508 with the BAK MX4 Tonneau Cover part # BAK48330 but the issue will be that the base rails of the ladder rack are going to interfere with the tonneau cover folding up.

  • Tonneau Cover Recommendation for 2018 Ford F-350 Short Bed with Fifth Wheel Hitch
    The BAKFlip MX4 part # BAK48330 that you referenced has 4 equal width sections that cover the truck bed. Since your truck bed is 6-3/4 feet long each section will be 20-1/4 inches wide. The other thing you need to consider is the heigth above the bed rails this cover adds when folded up and the potential for clearance issues between it and the overhang of the fifth wheel trailer. You'd need 6 inches between the cover and the trailer overhang at least. The RetraxPro part # RT80386 would...

    Usually ladder racks use the inside edge of the top of the bed site to attach to the vehicle, but luckily there are exceptions to that. The Thule TracRac SR is typically compatible with tonneau covers that mount to the inside edges of the truck bed. I spoke with my BAK Industries representative, who confirmed that the SR will work with the BAKFlip MX4 on your truck. The correct Thule TracRac SR for your short bed F350 is part # TH43003XT-785.

  • Can Thule TracRac Ladder Rack Fit with BAK X4 Revolver in 2019 Ford F-250 6-3/4 ft Bed
    The TracRack SR Ladder Rack part # TH43002XT-610 has enough clearance to allow the Bak Revolver tonneaus like the # BAK48330 you have installed on your 2019 Ford F-250 6-3/4 foot bed. This is a very common combination of ladder rack and tonneau cover that we know fits and works great together. Your Revolver is actually the only hard roll-up tonneau cover we can safely recommend as a fit with the TracRac SR ladder racks.

  • Will BAKFlip MX4 Cover Fit with B&W Companion on 2022 Ford F-350
    The BAKFlip MX4 Hard Tonneau Cover # BAK48330 sits about 1-1/2" below the top of the bed rails on your 2022 Ford F-350 Super Duty short bed. Since this is really close to the height of your B&W Companion # BWRVK3370. Because of this I recommend looking into the RetraxONE MX Hard Tonneau Cover # RT60383 instead. The tracks for this sit high enough to clear your 5th wheel and the cover is stored in a 13-1/2"x12" canister at the front of the bed. I really like this option as well because...
