Any body had issues with extremely loud whistling noise coming out of the side cockpit windows. We have a 2019 Thor Hurricane 29M with 3800 miles. On our first long trip we all of a sudden get a very high pitch whistling coming out of what we believe are the side widows. Starts at about 35 mph and increases with speed.
Checked the windows and even applied painters tape exposed leading edges, still getting the whistle. Forget any radio we are wearing foam earplugs to make driving bearable. On the road for another 3 weeks before we can get back to our dealer.
As others said spray the top, bottom, and side track. What's happening is the window is not closing all the way and the lock is slightly pushing on the window causing the noise. It looks closed but it can go a little bit further
For the other noise "dog house" issue search for threads for insulating it
I just had both side windows replaced under warranty. No amount of sealant or witch doctor chants worked. It turned out to be the frames were cracked which caused my howling sound. If you're under warranty have them checked out. My RV is a 2018 ACE 32.1.
