Product is great but the instructions online doesn’t match the truck I purchased the cover for. If the instructions were printed and proper for a 2026 Toyota Tundra, I would have had it installed with in 30 minutes.

The MX4 is very good in quality but should have printed instructions included. I started the project on a Saturday morning only to find out our cell and internet service was down. The only way to get the instructions is with a QR scan! This may be good for folks who live in the big city but not for us country folk. One of the latch screws were defective but now has a silver screw in it and works fine. The other thing I will say is with the MX4 on my 2023 Tundra I noticed a 2 MPG increase. Over all a very nice product but spend the extra 50 Cents and put instructions in the package!

I was surprised to find out Bak was sold to real truck, the top came with a long scratch on the back panel with a Small gouge out of the aluminum frame. The instructions I received didn't show where the weather stripping goes so I had to Google it to find out. It seems well made and I hope it lasts considering the price

Packing was perfect, cover was more lightweight than I thought. Cause I had experience in installing it was fairly simple. But instructions may need to be more specific or clear.

I really like the cover and the way it sits flush to the bed. I am disappointed that I cannot use the cargo tie down cleats that came as part of my Toyota Tundra management system. The rails sit so flush the cleats will not fit under them. Before I purchased this cover I did alot of research and watched installation videos. The videos I saw had rails that used the factory mounting holes and hardware for the factory cargo management system then you installed the removed factory rails to the ones supplied by Bak. This cover came with blocks that slide into the factory rails and you attached the supplied rails to these. It works very well but does not allow enough room for the cargo tie downs. Bummer.
