2013 Itasca Sunstar 30T Noise Help

I agree with make good use of your warrenty. You don't want to put a quick fix on something and have it become a problem after you are on your own. By taking it in you will at least get it posted in their system that the problem started under warrenty. However I really do not think that it is in your walls. Between the insulation and aluminum studs it is too tight for that kind of movement. Like said check your dining table. It could be your blinds slapping the wall if they are not attached tightly. Our blinds in the bath and kitchen are the standard aluminum mimi blinds which casn be noisy if not pulled up while in transit. Also check your couch seatbelts. If they are down in your couch loosely they could be hanging over the frame which will allow them to swing and hit the frame or wall. Have somebody sit in the bach when you hear the noise. They should be able to pin point it. But remenber a coach will never be as quiet as your car. Enjoy and use it every chance you get.
