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...
You will probably have to caulk the noisy opening. i had to caulk around my windshield due to some delam right behind it. I use painters tape to tape over the weep holes at the bottom of the side windows. It makes a huge difference. I remove them in the rain and when I'm not traveling. The blue makes it eaier to remember to remove it.
