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 find that I have a lot of wind noise sometimes. It all depends on which way the wind id blowing outside. If I am bucking a head wind it's bad, tail wind, quite as can be. Side winds depends how strong. I guess I have learned to live with it.
