I had one of these covers on my last truck, and loved it! My daughter had one installed on her new truck, as well.

Great cover. I traded in my 2019 Ram 1500 Limited for a 2020 Ram 2500 Laramie. The 1500 had the Undercover Ultra Flex and I had to have one on the 2020 Ram 2500. Best cover by far.

Very happy with the installation and the product. In a summer thunderstorm only a very tiny bit of water made its way in one one corner. I had a dually with a soft cover that was not nearly as nice.

This is the second Undercover folding hard tonneau cover I've owned. This first was on a 2007 F-150. It's still in great shape after 13 years of use in Alaska (9 years), New Mexico (2 years) and South Dakota (2 years). Now my grandson has it. You make an excellent product.

The cover looks amazing and it's easy to open and fold back to allow access to the truck bed. It's exactly what I was looking for. Hopefully it holds up for years to come. Time will tell.
