Features to know about
Full Bed Access: Quad-Fold Aluminum Panels
Some covers make it a hassle to haul large gear because they have to come off completely. The BAKFlip MX4 solves that with a quad-fold design. You can flip back as many panels as you need or fold them all up against the cab for full bed access. Prop rods hold the cover upright so you can drive with the bed open, and the integrated buckle system lets you secure it in the folded, flipped-up, or closed position without any loose straps or tools.
Everyday Protection: Rustproof Aluminum with Matte Finish
If you’re out in all weather, a durable cover is a must. The MX4 uses ½" thick, rustproof aluminum panels with a premium-density foam core that add strength without extra weight. It’s rated to hold up to 400 lbs of evenly distributed cargo, and the matte black finish resists scratches, scuffs, and UV rays so it stays looking sharp through years of use.
Keeps Cargo Dry: Seals and Drainage System
Rain and car washes can send water everywhere, but this cover is built to keep your gear dry. Matte-black rubber seals line the edges while a built-in drainage system channels water out of the bed. The rear seal lets you open or close the tailgate with the cover up or down, so you’re not fighting the weather just to load or unload.
Clean, Low-Profile Look: Inside-Rail Mounting
For a sleek finish that doesn’t stick out past the bed rails, the MX4 mounts flush inside the bed. The aerodynamic profile reduces drag and helps maintain a smooth look while you drive. Because it sits inside the rails, you still have access to stake-pocket-mounted accessories or raised side rails—a clean setup that’s practical, sturdy, and sharp.
Quick Installation and Secure Locking
There’s no drilling required—frame rails clamp to the inside of the bed, and included bolts secure the front hinge rail. Once in place, the automatically latching panels lock when the tailgate is closed, creating a secure bed space for tools or gear. It’s simple, strong, and ready to go right out of the box.

Ordered the BAKFlip MX4 for my son on 12/15 after calling to verify the tonneau would arrive by Christmas. Then received an email that said "Your order has been forwarded to one of our partners for direct shipment to you" and never received another shipping update or any tracking info. Finally on 12/22 I emailed Etrailer.com who told me they didn't know when I would get it. The Tonneau finally arrived on 12/29, 3 days after my son returned to California (he drove his truck, 2100 miles). He won't be back till next Christmas so I have to figure out how to return this product. I had several other buying options to get this here by Christmas, but went with Etrailer because of their reputation. This will be my last purchase from Etrailer.com.

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.

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.

Love that I can have a cover on my truck while towing a fifth wheel. It folds up nice and latches to stay out of the way of the fifth wheel hitch. Then I can keep items in the back of my truck while camping and they are secure (my tailgate locks).

I love how this tonneau cover works. because it allows use of almost the entire bed of the truck when it's fully open. I was a little disappointed with the clamps for installing the side rails, as they didn't seem as robust as the clamps in the cover I bought for my last truck. However, I am happy with its operation, and the fact that the truck bed is a locked compartment when I lock the tailgate.

Thanks for the great feedback! We're glad you're enjoying the tonneau cover and that being able to use almost the entire truck bed when it's open has been such a big plus. It's also nice knowing your gear stays secure when you lock the tailgate. We appreciate you mentioning the clamps too—that kind of feedback is always helpful. Thanks again, and we hope you keep enjoying your new cover!

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.

The bed cover has been great so far. Followed the instructions and took my time adjusting it and it has been working well. Keeps the bed dry and looks good. I did have to order an extra kit to get enough rail clamps. Once I put the extra clamps on it feels much more secure. For 8ft beds they need atleast 8 to 10 clamps, not 6. The cover has been working in that I don’t have to uncover the whole bed to use it. I just need to open up as much as I need at the time.

BAKFlip MX4 is a great addition to any pickup. It allows for secure transport of material, keeping it dry in bad weather and yet readily accessible with the flip of a panel. It also keeps the weather away from your 5th wheel hitch. Can be left on when towing.

I have been using this cover for almost a year now, and am very pleased with it. It looks and fits great, and it is secure and keeps most of the bed dry in the rain. A couple of rubber trip bits have needed some improved securing, and I used a little RTV so it was easy. I drove it across the country round trip last summer and it was perfect. I would recommend this cover for a great-looking and pretty secure cover. Finally, it is easy to fold forward when it is time to haul loads taller than the bed rails.

Purchased this BAKFlip for my new 22 RAM Classic 1500. Installation went well, instructions were good to follow, and it fit perfectly. One of the plastic hold down clips had a manufacturer defect with excess plastic mold residue inside the clip that prevented it from properly working. I sent an online warranty claim explaining the problem, and a new clip was sent to me in a reasonable amount of time, and it worked fine. After one year of using the cover, I am very happy with it. Everything functions as it should, and it is very versatile. While it is not 100% watertight, I mostly notice a small amount of leakage around the tailgate seal after washing the truck. Under normal rainy weather, there is no leakage, and we get plenty of rain in the PNW. My four-star rating rather than a 5 star is only because of the manufacturer defect and the curling of one of the rubber cushions on the underside of one of the panels where the adhesive holding it on the edges has not held up under the hot weather (with the black color, when the sun beats down on the cover it gets pretty toasty inside the truck bed with the cover closed). I am thinking that should be an easy fix by applying some good adhesive and taping in place until the adhesive cures. Just haven't gotten around to doing it. Again, really like this cover. Would recommend it to others, and if I ever have a need for one in the future, would definitely not hesitate getting another BAKflip.

The BAKFlip after 2 years is still functioning great. I fixed the curling cushion by applying some strong adhesive to the spots that had detached, taped it in place and let cure for a couple of days. That solved that issue. Would continue to recommend the BAKFlip to others.

- Ladder Rack Recommendation for Retrax Tonneau Cover to Use with Thule Hullavator TH898Hey Walt, since the Retrax Tonneau part # RTT-80383 that you referenced has T-slots for accessories you can use the Yakima Overhaul HD part # Y01151-5855 for a ladder rack and since the crossbars of this rack have channels of their own on top of them that would allow you to use the Thule Hullavator part # TH898.

With the Leer Hard Tonneau Cover # LE74FR folded all the way up into the standing position, it is designed to stay below the third brake light. I don't expect it will block your camera view, or at the very least, it may only block a small portion that isn't important for anything like hooking up. For your Reese Goosebox setup, the cover extends about 26" into the bed from the bulkhead when it's 3/4 open. I'd measure 26" back from the inside edge of your bulkhead...

We do carry the Bakflip MX4 model 448330 as part # BAK48330, but I am sorry to say that we do not offer replacement rails for this cover.

So what you would need for the new truck is the TracRac SR part # TH43003XT-785 and then for the tonneau cover part # BAK48330.

Since the BAKFlip MX4 completely installs within the bed rails of your truck, the Adarac Pro Series will be able to install into the stake pockets of your vehicle without interfering the tonneau.

The biggest being that the G2 has three sections that fold and the MX4 has 4. The MX4 is also compatible with the BakBox which is a storage box, part # BAK92100. The MX4 also has a weight rating of 400 lbs evenly distributed on it while the G2 isn't rated at all.

Since the cover sits against the back of the cab when folded up and reaches most of the way up to the roof, it would be a little too close for comfort to the front corners of your 5th wheel during turns.
