BAKFlip 448121 MX4 (GEN 3) Hard Folding Tonneau Fits 14-18 Silverado/Sierra 1500,15-19 2500/3500 6'6" Bed

Fairly easy install. The videos help a lot. I had a slight issue with the rails leaning down slightly after being tightened. This kept the latches from catching when unrolled. After re-installing several times to see if I'd done something wrong, I just used a pair channel locks and bent the rails ever so slightly where the latches would make contact. Just enough to get it to latch without actually being able to see it. Worked great from there out.

This is my 3rd BakFlip install over the past 9 years! I like how easy they are to install. I also like the low, clean appearance of the cover yet how secure they are from casual thieves etc. This new iteration feels lighter and better hinged. I like it!! My only complaint if you can call it that is that the 3 block bumpers have always resisted my attempts to peal the paper from the double sided tape that reveals the sticky side so you can install the bumps to the last panel that rest on the truck rear window. I can never get those to work properly.

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.

Cover was missing installation components …needed to wait on that . One of the clips on the rail is broken it has been sitting in FedEx “shipping label created” for a week. Really slow to just get it fully functional . Ensuring the install kit is complete replacing things broken in shipment should not take so long Bak is really slow

I specifically order this because it stated “rapid ship” and indicated it would ship on the day I placed the order. I waited for 4 days and there was no shipping information. It took forever to get through to customer service who could not resolve the issue. I waited a couple more days and was finally told it would ship the next day. Then I had and issue with one of the rubber bumpers that came off and again called customer service who said they would refer it to the BakFlip team and they would reach out to me. That was last week and I have yet to hear back from anyone.

Materials seem to be good quality. Bed cover is sturdy but does not adequately cover the bed. There are a few gaps that do not seal well. Will work well for keeping items safe from theft, but I would not recommend if you are looking for something that is watertight. It comes with drain tubes which can route a lot of water out of the bed, but a lot of water still ends up in the bed of the truck.

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.

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

This cover does not align properly for all latches to click into place with out manually pressing up on the rails and down on the cover at the same time. It requires modification to the bed of a 2025 tundra for the drain hose to fit. It also leaks significantly from the corners closest to the cab which causes water to puddle where the drain hose goes through the bed. The water will not drain from the bed because the hose occupies the drain holes. I had a gator cover and never had these issues. I have reached out to Real Truck and BAK for support but was told by BAK that I had to go through Real Truck but website says same company. Real Truck is unresponsive.

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.
