Item was easy for me and one of my grandchildren to install on my 2019 Ford F150 truck. I had to re-tighten the clamps after a month. This item adds to the good looks of the truck. There is some rainwater entry on the edge paralleling the cab however, it is not sufficient to bother me so far.

My Ultra Flex cover arrived with two broken pieces. 1) rail cover, at the end near the tailgate. 2) water drain spout. I used Epoxy to glue it. I spend almost $1000. & was not happy about the broken pieces and I didn’t want to ship it back because of the trouble involved in the process!

Install Time: 1-2 hours

Looks great, easy to install. Just a small amount of dampness in back corners so far but as I understand it is common with most covers. I am happy with this product.

Received product quickly, fits truck well and looks great. Have an issue with the side clamps holding the rails on, not extending up fully enough for a 100% grip to the side bed frame (I have no Toyota OEM rail). Maybe have three quarters grip and these will easily bend the truck bed lip/body if tightened too much. Another thing is the 2 camps that hold the cover to the bed at the bulkhead, did not fit into the rail as instructed so just clapped to the entire rail. Will look at it again when warmer out. Also, one supporter bar clamp that holds the core up was broken from shipping but autoaccessoriesgarage was quick to have the manufacture send a new one out. Really great service. 5 year warranty and the fact that the cover does not rest against the body were the deciding factors.

I've had this tonneau for about a month so far. Starting in February, held up great through sub zero temps and in snow. And so far light rain in March. Only a little bit of moisture has came through around the tailgate area. But don't think it was the cover's doing. My only gripe is the hardware, was missing a tab to unlock the cover when in the upright position.

The only issue was a poorly manufactured drivers side rail which had a large gap at the cab end that I had to fill with foam. Otherwise product looked good and installed easily.

It takes 2 to install efficiently, but I finished installation in about an hour by myself. Looks good and the light is a plus.

I am definitely happy with the quality of the cover and hardware, which are heavy and solid. The installation could have been easier but the instructions were not detailed enough in some areas and some of the pictures were too generic, which made matching the picture impossible. Unfortunately I wasn't in a position to watch the video but that sounds like good advice to me at this point. The one grip I have is the sizing. The cover BARELY fits my bed. The sides are okay as the rails fit pretty well and keep the top secure but the length is short. In the front, the rubber weather stripping is all that overlaps the front of my bed and the back just barely covers the front edge of my tailgate. I think it will be weather-proof but only barely. The latches in the back also barely engage so I'll have to see if they can be adjusted when I get a chance to look at it again. If not for the short length, this cover would have received 5 stars assuming I can adjust those latches.
