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.

This cover is great. My only wish is it could fit a little tighter side to side. I've had it 1 year and it has worked and held up perfectly.

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!

Fits perfect, looks great and virtually waterproof. Be careful, it can dent rather easily.

Still performing perfectly. Dents easily is an issue but otherwise perfect.

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.

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


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!

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.

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.

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


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.

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.

  • What is the Difference Between the BAKFlip G2 and MX4 for 2020 GMC Sierra 3500 Short Bed
    The 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...

    The BAKFlip F1 Hard Tonneau Cover - Folding - Aluminum and Fiberglass # BAK772133 and BAKFlip MX4 Hard Tonneau Cover - Folding - Aluminum - Matte Finish # BAK448133 are very similar but there are a few minor differences. The F1 has a rough texture that tends to hold up better against various conditions and does not get easily scratched or dented. The MX4 has a smoother appearance and texture and does not have a rough look or feel to it. I think the F1 looks better and it holds up better...

  • Adarac Ladder Rack Compatible With The BakFlip Mx4 Tonneau Cover On A 2021 Chevrolet Silverado 2500
    If you have the BackFlip MX4 # BAK448133 tonneau cover on your 2021 Chevrolet Silverado 2500 then you can use the Adarac Pro Series Ladder Rack # A4003991. You will need to get this rack because the towers holding the crossbar up is completely upright. These only come in silver. This one comes in black # A4004148 but won't work because of the towers tapering inward. You will most likely have contact with your first panel on your tonneau cover with the tower when you're folding it up.

  • Rapid Switch Pro On A 2021 GMC Sierra 2500 HD with 610 bed with Bakflip MX4
    The BakFlip MX4 is compatible with the Rapid Switch Ladder Rack # RS77FR. These systems work well together and the Rapid Switch System is the same for the 8 foot and 6-3/4 foot bed. For your tonneau cover, it all depends on the length of your bed. If you're wanting to get the BakFlip MX4 and you have a 8 foot bed, get this one # BAK24FR and if you have the 6-3/4 foot bed get this one # BAK448133. The rails are long enough to go from the bulkhead of the bed to the tailgate. I have an installation...
