After looking at similar products online I chose the Undercover Flex. The product is as advertised and I would recommend it. I installed it myself without any problems and it looks good on my truck. My only concern is with the front seal that is provided, in my opinion they could provide a better quality seal. The cover sits almost flush with the bed of the truck and in my opinion makes for a better look overall.

This is a very high quality product and really adds to the appearance of my 2019 F150. It was easy to install (even though) I am 73 years old. Hardest part was climbing in the back of the truck.

Install Time: 30-60 minutes

Great product and great service from AAG. Shipping was very fast. My only complaint is that the instructions weren't all that great and the cover rails needed to be installed 1/8" lower than the bed rail not flush or 1/8" higher as the instructions said. Other reviewers have said the same. After a little adjustment it fits and looks awesome with virtually no leaks. It probably took me an hour on the initial install because I had to lower the rails but I could re-install it in 15-20 minutes easily after having done it once. Thanks AAG for another great product!
