Cover is good but water gets in the bed area easily. Don't know if it is the remote tailgate release mechanism or what. 659519

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

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.

Review from a similar BAKFlip MX4 in Tonneau Covers
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

Review from a similar BAKFlip MX4 in Tonneau Covers
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

Review from a similar BAKFlip MX4 in Tonneau Covers
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

- Do the Truck Hero TS Rais Work with the Gator EFX CoversYes the TS Rails for Truck Hero Elevate Rack System part # TH65FR will work out well with your Gator EFX Tonneau Cover. The design of the Gator EFX is very similar to that of the BAKFlip MX4 Hard Tonneau Cover part # BAK448133 which is confirmed to fit with the TS Rails.
view full answer... - What is the Difference Between the BAKFlip G2 and MX4 for 2020 GMC Sierra 3500 Short BedThe main difference between the G2 # BAK226133 and the MX4 # BAK448133 is that the MX4 can remain latched in position when latching the tailgate. With the G2 the cover must be unlatched to latch the tailgate. This can become kind of a pain if you're leaving the cover in position for an extended period, but constantly at the tailgate. The G2 also has a glossy finish on it, while the MX4 has more of a matte finish and is generally a more sturdy cover when it comes to holding up over time. At...
