First, make sure you order
The right one. This amazon listing had reviews and photos for 2020 Ram 1500 with ram box... but it is not the right one for that. The review was on wrong item, so I was mislead and had to return the item. I went to the BAKFlip site and found right one.
That said, the return was simple and free, and my refund was posted about a week later.
Once you get the right model for your vehicle (use the BAKFlip sight to identify right model). You will be happy with this product. I have had it 3 weeks and it's awesome.
I installed alone within an hour. Extra hands would be nice. WATCH VIDEO - it's way more useful than instructions. Also be sure you get the instruction addendum for your model vehicle if it has one - that part is actually helpful. My model for 2020 Ram 1500 w/Rambox came with rails that slide onto manufacturer's t-slot rail system - so simple and perfect fit! Be sure to fully coat t-slot surface with liquid/foaming soap to help rail slide easily on. Otherwise it slides partially on and then gets stuck and hard to move either direction.
Very well engineered and perfect fit for my model. So perfect, it Seems like it would have come from manufacturer. I got the FiberMax hard trifold and it seems to deliver on the promise of being durable and secure enough for valuable items. (Of course any determined thief will always find a away). But this is difficult enough to get into that it should deter most would-be thieves.
Loving it so far, and loving that it doesn't flap around, rattle, or make noise when going highway speeds... like vinyl soft tops I use to have.
Mine was $1150, which is expensive, but this is a nice piece of quality engineering and security.. will be worth it if it lasts longer than vinyl covers.

I installed this Bakflip MX4 on my 20' RAM. It was easy to install. Looks great!! So much better than the soft roll up cover. Very durable. Locks in place to protect what I have in the bed. I'm very happy with this purchase.!!

This is the 3rd BakFlip I've purchased for one of my trucks, my F-150 was the first to get outfitted with a BakFlip and when the time came to outfit my Ram 2500 it was a no brainer. This past week I traded the F150 for a new 2020 RAM 1500 and again the 1st item purchased was a BakFlip!

The install is quite easy, it takes about 30 minutes doing it solo, having someone else onhand only makes mounting the bed rails easier but doesn't make anything faster.

Minimal tools required, 1 socket wrench to tighten all 6 bolts and screwdriver for the latches, that's really all you need other than a steady hand to secure the rails to the bed making sure they are totally flat and forward, again this is where another set of hands can help.

If you don't read instructions, make sure you attach the strap snaps to the tonneau before you mount the tonneau to your truck bed, it's hard to put the thing together once mounted, also it's best to run the drain lines into the bed before you mount the tonneau and just after you attach the rails, just makes it easier.

The tonneau can be installed by 1 person when the time comes, the hardest part is just getting it from the ground and onto the rails, don't open it beyond where it shipped and you'll be able to push it into position. The bolts that secure the tonneau to the rails are best installed top down so you can wrangle the cover front to back and left to right a little to get it into position.

When the time comes to secure the bolts to the rail, 2 approaches work, one is to have someone outside pushing down a little while you lay in the truck bed looking up to set the washer and lock washer onto the bolt or you can do it solo, again not hard just easier to have someone there. BE CAREFUL NOT TO OVERTIGHTEN!!! If you overtighten you can easily make the fiberglass cave in and you'll leave a dent that you will regret. Also, spend some time in the bed adjusting the front back so that the cover lines up flush with the truck bed on the INSIDE and clean the surface before you install the 3M foam so that it stays in place. I opted to get a better foam tape from Amazon when I did my 2nd truck and 3rd truck because I knew that a rubber gasket offered a better seal but that's not necessary for most.

Finally, once you close the entire tonneau, open it pulling the cord on one side, it should release both sides, if not you may need to adjust the latches (simple screw and alignment) to they are not so far under the rail that you can't open them from only 1 side. Again this is from experience and on my 1500 I had to do this because I found that I could not open the cover that way. A simple 1-minute adjustment and I still have a solid latch but I can open it with 1 hand.

These are great covers, we were in a hail storm in South Dakota last year and my 2500 was exposed, oddly enough the only damage was on the tonneau, the truck took 3 small hits which to me are beauty marks, the tonneau got dimpled quite a bit but didn't' need replacing. This was not monster-sized hail, only pellets but none the less, the BakFlip protected all our camping gear.

One question I've been asked a number of times does it leak, the simple answer is a little, it's not a 100% perfect seal, I can take it to the car wash and there will be a little water inside but not a puddle. It does a surprisingly great job of keeping water out so if you're ok with a little and I stress a very small amount, you'll be fine with this cover.

Very good cover. Secure and virtually waterproof, only a small amount of leaking at the tailgate. A few weird design issues like very sharp edges at the tailgate and a gap also at the tailgate. I used black gasket material to seal the gap. Overall I love the cover, it us really easy to open and close and looks really good.

Packaged well seller to prevent damage during shipping. Extremely easy 40 minute install. Opens and closes with ease. Flush fit on bed makes it look really nice. Covering the bed has increased my gas mileage. Went through car wash and no leaks with the exception on each side of where the tailgate has minor gap on each side, small amount of water dripped down. This is not the fault of the tonneau cover, it's a design issue with Ram. Probably could seal it with a small piece of weather stripping. I researched many brands and found Bakflip MX4 to be superior. Highly recommended it for 2022 Ram 1500. Also, delivery from the seller was a day earlier than anticipated. You can't go wrong with the Bakflip MX4.
