Texas Silver

That's exactly what it was! So mounting further back fixes it? It won't be back on for a few weeks but I'll keep that in mind. Thanks!

New here as well but wanted to chime in on the Tonno Pro tri-fold cover. https://www.amazon.com/gp/product/B00EUZZK74/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1 I ordered one last week and took my first trip with it on over the weekend. Drove from Arlington to Austin, Tx. It is a little noisy on the highway once you get up to 75+. The tri-fold is very convenient and goes off and on quickly. Seal seems good. Took it through the car wash and bed was pretty dry afterwards. I do not plan on using this very often and pretty much only for trips with cab fully occupied and luggage goes in the bed or tailgating and in need of the security when in the game. The trifold and snap buckles make on/off easy and storage in the garage when not in use is perfect for what I needed. Easily worthy the price but if it was going to be on 100% of the time, I would need to focus on the noise and make it stop.
