4.0 out of 5 stars BakFlip MX4 installed on my 2019 GMC AT4
Reviewed in the United States on 17 January 2019
Overall I am pleased with my BakFlip MX4. I selected the MX4 because I wanted a cover that didn’t block the review mirror camera when the cover was folded open. I am please to say this unit works perfectly for this purpose. I just installed it on my new GMC Sierra AT4 by myself in about 30 min. The installation was extremely easy. After watching the installation video I didn't even bother to open the instructions that came in the box. Seems secure but it will not be water/dust tight due to the shape of the self opening lift gate with built in step. As you can see in the photos the cover does not seal to the bed. I may try to use some of the gasket material provided to see if that helps. If there is excessive flooding or other possible issues I will come back and update my review.

1.0 out of 5 stars Great concept, easy to install
Reviewed in the United States on 17 April 2018
Great concept, easy to install, and the product does look good. Unfortunately the 1st delivery had a tear in weather seal on passenger side. Easy to order the replacement, it did arrive in a short time span but yet again it too had a ripped weather seal at the same location. The middle fold of the drivers side. This second one is less noticeable. Needless to say I was becoming a bit frustrated. That frustration doubled when I learned that I would have to pay UPS to pickup the original defective product. So I loaded the 65 lb box into the back of the truck and drove over to UPS for drop off. Can't believe that Amazon would not pay for the pickup of the defective product. This is the worst experience I've ever had with products ordered through Amazon.
