My son and I took a RV for a test drive and it was so loud we could not hear each other. When we got back to the dealer we found out that the door was warped and the windows were not closing properly. A year later took my Majestic 19G for its test drive and I was shocked by how quiet it was. bought it and when I left the lot after buying it I was 10 minutes away from the dealer and the noise got really bad. Took me half an hour to find a safe place to pull over and I was almost in tears it was so loud. Checked the windows, vents, door and everything seemed good. Then I decided to open and close EVERYTHING. Vents were good, door was fine but the window behind the drivers seat was open the slightest. Cleaned the track as best I could and slide it closed and the noise was gone. It still comes open occasionally and I laugh about it now.
I also added carpet and underlay for warmth but it sure cuts down on road noise as well!
