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

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

  • Is BAKFlip MX4 Hard Tonneau Cover for 2016 Ford F-150 With 5-1/2 Foot Bed the Latest Version
    I checked and the MX4 we carry for your 2016 Ford F-150 with a 5-1/2 foot bed is the updated version, the BAKFlip MX4 Hard Tonneau Cover # BAK48329. Ordering this will get you the latest version for your F-150.

  • Recommended Ladder Rack for 2019 Ford F-150 Equipped with Gator Fold-Up Tonneau Cover
    We don't currently carry Gator Tonneau Covers but in my research I found quite a few styles available for your 2019 Ford F-150. Whether or not a ladder rack can be added with this cover in place will depend on exactly how your particular tonneau cover installs. If the cover sits completely inside the bed rails on your truck and doesn't overlap the top then I highly recommend the Adarac Pro Series Custom Ladder Rack; part # A4000964 if you have the 5-1/2 foot bed, # A4000946 if you have...

  • Best Ladder Rack for 2017 Ford F-150 With 5-1/2 Foot Bed and BakFlip MX4 Tonneau Cover
    The best option to install a ladder rack on your 2017 Ford F-150 with a 5-1/2 foot bed and the BAKFlip MX4 Hard Tonneau Cover # BAK48329 is the Adarac Pro Series Custom Truck Bed Ladder Rack # A4000964. The reason for this is the Adarac sits fully on the bed rails of your '17 F-150 and won't overlap to come in contact with your MX4 and the arms on the Adarac are wide enough that you can fold your tonneau up without it coming into contact with the rack.

  • Will BAKFlip MX4 Folding Cover Fit a 2018 Ford F-150 5-1/2' Bed with Adarac Pro Series Ladder Rack
    Since the arms of the Adarac Pro Series # A4000964 do not sit at an angle you will be able to use the BAKFlip MX4 # BAK48329 on your 2018 Ford F-150 with a 5-1/2' bed. If you check out the linked review video for the ladder rack you can see that it fits perfectly with the Lomax # AB1010019 hard folding cover which is just a different brand of the BAKFlip MX4.

  • Ladder Rack Compatible with BAK Revolver X4 Tonneau Cover on 2019 Ford F-150 w/ 6-1/2 Foot Bed
    The Adarac Pro Series # A4000946 Ladder Rack would indeed be compatible with a BAK Revolver X4 roll up tonneau. The uprights of the ladder rack are perpendicular to the bed sides, so they'll allow the cover to roll up without interference. I've linked you to a product demonstration video featuring the # A4000946 Adarac Pro Series Ladder Rack.

  • Will the Thule TracRac SR Work with the BAKFlip MX4 on a 2018 Ford F-150 5-1/2 Foot Bed
    I do have some options for you but the Thule TracRac SR Sliding Truck Bed Ladder Rack part # TH43002XT-508 and the BAKFlip MX4 Hard Tonneau Cover part # BAK48329 are not a good fit. The rails on the SR are rather wide so they would likely overlap with the seals on the MX4. In addition to this, you would need to move the rear rack forward in order to fold the cover up each time and with continuous use the seals on the cover will wear out. The only tonneau cover that we know for sure works...

  • Ladder Rack Recommendation for a 2018 Ford F-150 5-1/2 Foot Bed with Tri-Fold Tonneau Cover
    The Adarac Pro Series Custom Truck Bed Ladder Rack part # A4000964 which is a fit for your 2018 Ford F-150 will work with your existing tonneau cover so long as it does not cover the stake pocket holes. The BAKFlip MX4 Hard Tonneau Cover part # BAK48329 for example does not cover the stake pocket holes. If your tonneau cover does cover the stake pocket holes then there would be no way to install a rack over this and your only option would be a roof rack, the Rhino-Rack Vortex Aero Crossbar...

    I have some great options for you to use both a tonneau cover and ladder rack on a 2020 Ford F-150 with 5-1/2' bed. However, the best option for you will come down to what you will be using the ladder rack for, utility (lumber/ladders etc.) or recreational (kayaks/bikes etc.). Also, keep in mind that using a tonneau cover and ladder rack together can be tricky as they both generally occupy the same space therefore you will need to follow the combos that I have listed for you below as these...

    I have a solution for you, but because the BAKFlip MX4 # BAK48329 is a folding hard tonneau cover, you don't really have options as much as a single solution. The only ladder rack that we have confirmed for use with the MX4 is the Adarac Pro Series # A4000955 that you were looking at, since the uprights on the Adarac are not tilted inwards like they are on many other ladder racks. The Adarac Pro Series has a 500-lbs capacity and will allow you to carry your kayaks on the crossbars of the...

  • Total Weight of the BAKFlip F1 and MX4 Tonneau Covers
    I called BAK industries to see if they had weight specifications for their tonneau covers. Unfortunately, they do not record these, but there is something that I can offer that might help. The BAKFlip F1, part # BAK72329, and the MX4, part # BAK48329, for your 2020 Ford F-150 short bed both list their shipping weights as 71 pounds. So, accounting for packing material, boxes, etc., both of these tonneau covers should weigh around 64 - 68 pounds. I know this isn't exact, but hopefully...

  • Will Adarac Pro Series Rack Work With BAKFlip MX4 Cover On 2020 Ford F-150 5-1/2' Bed
    Yes, the Adarac Pro Series Custom Truck Bed Ladder Rack part # A4000964 will work with the BAKFlip MX4 Hard Tonneau Cover part # BAK48329 on a 2020 Ford F-150 5-1/2' Bed. In fact, it is the only ladder rack which will allow for full unimpeded use. The base rail for the ladder rack should butt right up against the gasket for the tonneau but if need be the rail can actually sit on top of the gasket without damaging it and letting water in. This is a very common duo so I'm sure you'll be happy...
