I needed a new cover for my new Denali pickup. I shopped many other brands and watched many videos on other covers. I decided to buy the the BAKFlip MX4 cover. I watch videos on how to install it and it installed pretty easy. Took me about an hour and a half because I am so particular. I love the way the cover looks. I also like how it folds. It locks down each section. You can also fold it up against the window to give you all the bedspace. I am very happy with my purchase.
I really tried my best with help to make the side rail square with bed sides. The foam strip seems to put the rail at an angle. I loosened/tighted the rails to no avail. The cover does leak but not excessively but it leaks. Any advice would be appreciated. S.
The cover is of high quality and fit the truck nicely. I had a Revolver roll-up cover on my previous truck and really liked it as well, but thought I would try a fold up on this truck. Fit and finish is nice. The only issue I have is my truck (and my previous truck as well) has Ram Boxes. While the cover fits good, there are gaps on both sides at the tailgate that lets in quite a bit of water. This was not the case with the Revolver cover (It let a small amount). I do wonder if there is a solution to this. Other than that the cover is awesome.
Cover is good overall. The instructions could be clearer on the clamping the rails down section. Overall it looks good. However I had a bumper peice fall off already. The one that sits flush on top of the cover by the cab window when not in use. Hopefully it lasts a long time.
I have the newer version bakflip mx4 for a 22 tacoma. First of they sent it to me with missing parts then it took them weeks to send them to me. The bed cover is ok. Installation was a nightmare to get everything on properly, and still somehow one side sits a 1/4 inch higher by the tailgate. It should come over the tailgate further and sit lower also, water is able to get in that space and someone could stick something in there to hook around the cable to open the bed cover. Overall it all just seems overpriced, every aspect of the bed cover and experience feels like it should be half the price. After doing some research it sounds like this product is going down hill from what it used to be, driven by the greedy people behind it I imagine. I would recommend looking elsewhere, I'm sure there are more affordable and/or better quality options out there.
I tried to communicate this with Realtruck, but there was too much red tape to make it worthwhile. There is a MAJOR issue with the written instructions that come with the cover that I purchased. No where in the instructions does it say that the clamps that hold the rail onto the bed should snap into the rail. If you don't snap them into the rail then the whole thing does not work at all. It will not latch and close up. I had to search Youtube in order to find this.
I ordered my part almost a month ago. I have not received it. I tried numerous times to get an update with no success. I am heading out for an extended trip and I needed the topper. Now I have to consider not having the part I needed for my trip. To add insult to injury I am being asked how I like the part I never receive. Kind of silly. Not a great first experience of a company that is “apparently” highly regarded. I am not a person of high expectations I just would like to know if I will get my part in time to install it before my trip. They took my payment. Will they be just as eager to return it? We shall see in 2 days when I will demand a refund.
This company knowingly shipped me the bakflip mx4 with rails that didn't fit my truck (2024 Tacoma 5') with zero communication. When I contacted them they say the rails are under review and no ship date is planned. Total scam! Do not buy from these folks and stay away from bakflip if you plan to actually have this system on your truck
I originally had a cover bought off amazon and it fits perfectly. I wanted to have a stronger cover and tried this one. However, water seeps in when it rains and in carwashes. My original cover bought cheaper from amazon doesn't do that. I hope they created it a little 0. 5 longer. Waste of $$$$.
I had a 2017 Ridgeline and loved the Bakflip. Purchased 2025 Ridgeline and a new Bakflip and could not get it mounted - rails are not as sturdy and I found others online with similar issues. Went back and mounted the 2017 Bakflip onto the 2025 Ridgeline and it was simple and easy. RealTruck really needs to look at the design of the rail systems.
