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.

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.

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


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


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


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.




by:

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.

This is my second purchase from etrailer. I have purchased two hard Tonneau covers for two separate trucks. I have been very happy with both purchases and have nothing but excellent service from etrailer.

Review from a similar BAKFlip MX4 Tonneau Cover 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.

Review from a similar BAKFlip MX4 Tonneau Cover 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!

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.

The cover has been great. I would buy it again. The only gripe from me is that for some unknown reason, one screw rusted ( as shown in the attached photo ). Why one, and not the other 3 ?? who knows...

Review from a similar BAKFlip MX4 Tonneau Cover 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.


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
$302.44
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 Tonneau Cover in Tonneau Covers


Works great and 5th wheel hitch fits underneath and when folded up I can hitch up my trailer without removing cover. Only issue is the corner pieces on the end section came off and I can’t get manufacturer to help me get replacement.

Review from a similar BAKFlip MX4 Tonneau Cover in Tonneau Covers


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

Review from a similar BAKFlip MX4 Tonneau Cover in Tonneau Covers


I am so happy I purchased this BAKFlip. The installations were perfectly understandable which is a big deal to me and the actual installation was easily completed. I did need my wife to help tighten two screws but otherwise I completed the job without assistance in about one hour. After using the BAKFlip for approximately one year I haven't needed to make any adjustments to the product and it works perfectly and looks new. I believe having the BAKFlip has made my personal property in the truck bed more secure in addition to being out of sight. This product has exceeded my expectations and made me very happy. I would purchase this again without hesitation.

  • Hard Tonneau Cover Compatible With Thule TracRac SR for 2015 GMC 2500HD w/6.5 Bed
    From your picture, it looks like this is possible and might not affect the use of a folding hard tonneau cover like the BAK Flip MX4 # BAK448333 or the BAK Flip F1 # BAK72122 , but the main issue may not be the rail as much as it is the slanted profile of the ladder rack load bars and them interfering with the folding of the tonneau. You may be able to slide the ladder rack around and make it work, but I'm not sure that it really provides a convenient working situation. I'll also add that...
