We took delivery on a new 2014 Sunstar recently and have a great deal of wind noise (driver side of the MH window) Took it in to CW and they were really perplexed by it but said they would work on it....
I experienced the wind noise on a trip coming back from TX. Going out was OK, no noise. It was terrible. I put some black caulking around the frame where it appeared to be have a slight opening. It helped some. Tried tightening the screws which held the frame, no luck. I finally just put an ear plug in. I was driving. Fortunately, my DH is hard of hearing. He was in the passenger seat and never heard it all. 2009 Hurricane, Class A. Unit since traded.
