The cover was simple to install, it works as advertised, and fit perfectly. It is one of the best gifts I have ever given myself.

Good cover but not perfect rain resistance

The back corners do not seal up well so water gets in there. I will try to fill in the open space with some weather stripping. I think it's a good value, though. I was expecting a hand actuated pivoting lock for the first (closest to cab) section of the cover but it was a tension cable like the other two hinges. that was disappointing but not a deal breaker.

The cover came to me in 7 days. It was easy to install in 1 hour by myself. I watched a youtube video and did it myself. The rail even is marked were to put the clamps. It performed just as advertised.

I agree with other's that an extra set of hands would be recommended, however I found a clamp worked ok. Directions for attaching the front part to the bed (directly under the back window) was not as clear as I think it could've been...had to call tech support....but that onlytook maybe 1 minute...counting from when i dialed the number until my question was answered!!!! I highly recommend this cover!

After reading other reviews I was a little iffy. I had read that it would leak a lot, but so far even in torrential rain maybe a few drops by the tailgate. When installing make sure to pull the rails down so the rubber sits tight on the bed caps. It had everything I needed in a cover, fill access to the bed and low profile design. So far I love it

Love it!

Simple install, lightweight, and keeps your stuff dry! It only took me about an hour and a half or so to install. Worth every penny!
