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!

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.

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


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.

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
$313.42
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


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.

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!

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.

Review from a similar BAKFlip MX4 Tonneau Cover 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.

Review from a similar BAKFlip MX4 Tonneau Cover in Tonneau Covers


This is my second Bak-flip bed cover. First one (aluminum) was on an F-150, second (fiberglass) on a Nissan Frontier. Both have been wonderful, and almost completely leak-free. Only place water has ever gotten in, is at the back corners near the tail gate, and that was only at the car wash. Installation was a snap, and operation has been flawless. Only thing that I would like different is an optional window in each panel, so when it's folded all the way up, you could see your load in the rear view mirror. You know, to make sure it's still there. I recommend getting the fiberglass over the aluminum, if you live in an area where hail larger than pea-size is a possibility. Great product.

Review from a similar BAKFlip MX4 Tonneau Cover in Tonneau Covers


My 15 year old and I installed the BAKFlip MX4 in less than 20 minutes. My RAM 1500 Crewcab has the 5'7" short bed with a factory drop in bedliner and this cover fit with a 1/64" too spare. I thought I might have to trim the rails, but no; it was designed to accommodate the bedliner. It looks good, fits well, is easy to operate, and is quite sturdy. Overall a quality product and I am quite happy with my purchase. Not too mention that the folks at etrailer provide great service all around making the whole purchase and installation an enjoyable experience.

Review from a similar BAKFlip MX4 Tonneau Cover in Tonneau Covers


well, two things that made it be a three star. On your ordering system for a Nissan titan you ask if it has the utilitrac system, I clicked on that, thinking that , there would be some kind of special adapters or something to fit the two together. There wasn't anything out of the ordinary, ( I guess I should apologize for not having an f-150). Anyway I had to take off the rails , for which anyone that has done that will know that the bolts are extremely difficult to remove, they are locktight in, and the bolts require a star wrench. Some of them I simply could not remove with the wrench, but had to grind the heads off to get them out. The other thing that was and still is annoying is the, prop rods do not fit in the slot with out bumping up the locking holder past the rivets, for which I have to get a wrench every time to do that. Not a lot of work to do that but it just doesn't seem right.

    'How dry' is kind of a subjective term that's pretty hard to define. Let me begin by saying that your average tonneau cover will do a pretty decent job of keeping the vast majority of the water out, but no Tonneau cover is completely waterproof. If you're having a heavy-type rain, chances are some water will infiltrate into the truck bed. A high quality cover like the BAK MX4 you mentioned will preform better than average in this respect.
