I'm still relatively new to the Class A scene. After about 4,000 miles on the road, I'm starting to wonder if the crazy loud wind noise around the windshield is normal. It is really loud on both sides...
I have the same model, although it's a 19. And I do not have that issue. Winnebago is one of the few A's which use a full metal cage up front and an automotive type windshield. (i.e., no gaskets). I think you might need a re-seal somewhere.
