Perfect product! easy to install! Beautiful addition to my 2008 Dodge Ram 1500.
I am so glad that I made this $1039.00 purchase. There are other, cheaper tonneau covers available on Amazon, but I received input from a professional installer that this was the top-of-the-line cover and I believed it and made the purchase. I am so glad I spent the extra money and got this BAKFlip MX4 cover for my 2008 Dodge Ram 1500. It was a perfect fit, easy to install, is really beautiful, totally functional, and is the perfect cover. I DO RECOMMEND this product for anyone who wants a beautiful, secure, water-tight, easily-accessible, easy-to-install, and sturdy, five-year warranty for a cover. One may spend only a couple hundred dollars on a tonneau cover but one really does get what one pays for. This is the tonneau cover for the discerning pickup truck owner. You will not be disappointed with this purchase even if the initial price is a choking point. It is worth the money!!!

Super high quality and no-drill install
Installed it myself on a 2021 Ram 2500. It was a perfect fit right off the bat and took a little over half an hour to complete. Amazingly high quality and super strong. I live in the Pacific Northwest and of course it poured rain about an hour after I installed it. Checked this morning and zero leaks! If you have a problem with a panel hanging up as you try to open it, read on! Quick shout out to their customer service. The rear panel was hanging up when I tried to unlatch it but all the other panels were fine so I knew I had it on straight. I called customer service and they instantly knew what the problem was and gave me the solution. The depth of the white latches can be adjusted. I did so and now it opens and closes as smoothly as any car door.

Nice Product - No Regrets
Overall, a nice product and I would buy again. As for the question / rating about water resistance - I can't speak to that as of yet, since it is a new install and hasn't been water tested. As for the rest - the installation is fairly simple and the cover is strong and robust. Some things to watch: * Make sure to use the shims if the rails sit at a slight angle, due to some curvature of the bed rails - if they sit at a slight angle, you may have issues with the seal properly contacting the tailgate. There is a supplemental sheet that includes shims and tells you how to use them. Your truck may or may not need them. * They say to install the bulkhead seal as one of the first steps. The install instructions don't clearly specify if the seal should be at the front, rear, or centered on the bulkhead (although the video does say to place it on the edge closes to the rear). I would wait and do this at a later step - for my truck, the bulkhead seal needed to be just a little bit away from the rear edge - meaning I had to remove it and reinstall it (this impacts the adhesive quality!). Its best to fit the cover first, then determine the exact location of the seal. Once the cover is properly fitted and in place, it will be very obvious where the seal needs to be - then you can easily lift off the cover (before securing it) and add the seal. Not having the seal does impact the general install and fitment of the cover - you just need to add the seal before bolting the cover down at the front. * Keep in mind - you don't need the bulkhead seal if you have a drop in bed liner that covers the bulkhead. If the bulkhead surface is painted metal - you need the seal. * While installing the rails, start at the middle (place the first clamp in the middle). I used a vice-grips to initially hold the rail in place - I didn't have a helper and this made it easy for me to keep the rail in place before installing the first clamp. * On the rear panel, I had an issue that required me to remove the latches on both sides of the cover / rear panel, reposition, and reinstall with the sheet metal screws (I used my screw gun for this - but be careful not to strip and over-tighten). The latches were installed with some adjustment capability, but not enough. The latches were sticking out too far and hitting the rails! At first I thought that my rails weren't all the way in - I confirmed this wasn't the issue. A look at the latches on the rear panel compared to the latches on the center latching panel clearly depicted my issue - the latches on the center panel (exact same type of latches) were further in, allowing clearance from the rail. The latches on the rear panel were clearly misadjusted and sticking out too far towards the rails. Again, I didn't have enough adjustment on the latches to compensate. This was fairly simple to do - took an extra 5 or 10 minutes (after figuring out the issue). But this shouldn't have been necessary. If yours sticks - check the rails before moving any latches. You want to make sure the rails are properly seated - otherwise they can interfere with the panels. Overall, nice product and nice look! Hopefully it does a good job repelling water - I have heard feedback both ways. I didn't want to rate that particular function as I haven't tested it. Overall, it took less than an hour to install - even with the minor latch issue. I installed myself without a helper.

Very happy with this purchase
This is a very attractive and sturdy cover. It was fairly easy to install, too. I have never installed my own tonneau cover before and it took me a little over an hour to install this one, start to finish. Instructions were reasonably good, with helpful diagrams. It was well-packaged for shipping, to protect it. I have only had it on my truck for a couple days, but I really like how well it works. Very solid. It hasnโt rained yet, and no cover is completely waterproof, but this appears as though it will keep items in the bed dry and protected from the elements. I got the matte black and it is really good-looking.

Itโs ok, not great. Overpriced.
Doesnโt seal well no matter how much adjusting you do. Itโs ok, probably the best product like this, but I wish there was something out there better. Definitely overpriced.

Top of the line
This is a really nice product. I am very satisfied and happy I spent the extra money. I expect to get years and years out of the topper. As advertised, solid, quality materials, easy install. Looks great on the 2019 Ram power wagon 2500 HD. I had no issues with delivery or product parts. With so many choices on the market, this one fits all my needs and wonโt limit the use of the pick up bed. Go for it.

Fits 2022 RAM 2500 crew cab with 6'4" bed.
A quality product that was easy to install. I watched a short YouTube video on installation which gave some helpful hints on single person installation. Total install time was less then an hour without a second set of hands. I noticed some tiny drips of water after going through the car wash and again I noticed a tiny amount of water after a weekend of storming. Over all, this cover is very water resistant and I'm very pleased with it. 10/10 would recommend to any one looking for a hardened flip up cover.
