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.
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.
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.
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 just installed my cover and it looks great. It was a very easy installation. The only part about the cover I dislike is once I put the cover on and looked around the whole thing the spots where it folds were a little torn up. Being brand new that shouldn't be like that.
Installation was much more difficult for the Maverick than what is indicated in the Realtruck video. For $1200 it would have been helpful for an instruction sheet specifically for this model to be included. The tolerances for the Bakflip are so precise that any small imperfections in the truck bed are problematic. The drivers side latched perfectly but the passenger side would not latch for all three latches. Yes, the railing was installed correctly and identically on both sides. Determined that the truck bed was slightly leaning in on the passenger side. Had to correct by placing a flat washer as a shim under each latching mechanism. Also, the thick pads included to protect the cab are not thick enough for the Maverick. When the bed cover is flipped up it rests on the cab and the pads do not reach the cab. The rear window is recessed from the cab frame and the pads do not reach the window. The only place where the pads would actually work are on the very edge of the cover, and then it would not be able to close.
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.
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 $$$$.
Well let's see. It's been over a month since I placed my order. When I placed my order, the product was supposedly in stock and ready to ship. Still nothing. I am going to cancel my order and get the same bed cover from someone else. But since you asked for a review, here it is.
This isn't a review of the cover because you never sent it to me. A week after I ordered the cover it still showed as Pending Fulfillment. I called customer service and they said they'd get back to me. A week later they still hadn't gotten back to me so I bought the same cover from another online retailer and got it the next day. I cancelled the order from Realtruck and it still shows as Pending cancellation. I called customer service and was told they'd take care of it. Two days later there's no change. I won't be buying anything from Realtruck in the future.
