Factory 2017 Tonneau Cover loose by tailgate

The front is rock solid but the back can be lifted up about an inch. Is there a way to adjust this tighter? I took off the cover by the catch pins and they don't appear to adjust. Thank you kindly.

I remember someone having this issue but they found out they weren't fully pushing down and locking the rear in. Not sure if there is an actual adjustment. Maybe the mount itself?

 

If I remember correctly, you have to open tailgate, close cover and press securely, then close tailgate. I looked at this at the dealer when trying to figure out what options I wanted. There are much better aftermarket bed covers out there.

 

Thank you VERY much you were absolutely right. I needed to close it first but then also give it a pretty good slam and it closes tight. I know a lot of folks diss this cover and I had owned a Extang Solid Fold which was really good but I don't find this cover bad at all. My solid fold worked the same way but I guess time will tell. I do like that it's covered under the 3/36 warranty also. Thanks again for the tip you really fixed me up!

 

No problem, that's what this forum is all about.
