Love this cover

I purchased the UnderCover Elite Tonneau Cover. It fit perfect on the 5. 5ft bed of my 2023 Toyota Tundra. The initial assembly was simple. The cover itself allows for opening/closing with absolutely ease. It locks up with a key to keep our belongings SAFE and DRY during rainy weather. With all the different brands of tonneau covers out there, this one takes the cake ;)

New 25 Sierra 1500 Install

Looks and works great. The “scan for installation directions” kind of took me in a circle, but it was easy enough to google it and figure it out myself. Not terribly complicated to begin with. Installed by myself (I'm a big guy), but I would recommend a friend to help lift into place, then help with fine tuning the alignment. Still it took me about an hour. Looks and works great.

Good.

Looks good and doesn't leak in the car wash. This is the second of these that I have purchased. the first one was 10 years ago and I never had any problems.
