I have a new 2017 Winnebago Journey. I love it except for one thing - wind noise. I can't pin point exactly where it is coming from, but it seems like the front left, maybe the angle of the mirrors? ...
I had this problem with my Newmar Bay Star when I picked it up. I could not stop he wind noise no matter what I did. I picked up two wind deflectors for the sun roof on and auto and attached them just in front of the mirrors to reroute the wind and Shazam, the noise was gone.
