We are having a noise over the drivers head, sounds like the bubble top is bouncing, anyone else have a noise problem

Our 2008 Siesta 24 SA had a noise for months sometimes while driving that was driving me nuts that I swore was overhead. My wife would try to find it but could not determine where it was coming from. One day while going back to get something from the kitchen she said it sounded like it was coming from the side entry door. We found it was the screen door making the noise if the door was not closed fully. Slamming the door a little harder and problem solved.
It sure sounded like it was overhead.
Hope this helps;
