First off I know nothing about |Tonneau covers, I have trucks all my life but never put one on.
Anyway I thought I would try one (mainly used for travelling with the TT) and I wanted something I could take off quickly and by myself. The trifold type soft covers seemed to fit the bill, light weight easy off and nothing left on the truck.
I installed one yesterday and took it for a highway drive and I could hear the cover, a drum like sound from the vinyl vibrating. Today it was very windy (40 -50 mph) and the cover was loud when driving parallel to the wind.
Do all the soft covers do this?
The cover is very tight maybe that's part of the problem?
Thanks

 

My Extang Full tilt is quite as can be driving in side winds head winds and rear winds.

 

 

I have a Paragon. Its aluminum easy to remove by 1 person. No noise, has double locks.

 

I just talked to the Tonneau manufacturing rep. and they think I had the cover too far forward and air was getting under the cover. She said it was common problem with the Ford's and the new Rams. I will adjust it see if it fixes the problem. If not back it goes.
