For the first time in 4 years I had the opportunity to use the potty while my wife was driving....really had to go! There is a noise that was coming from under the bathroom area (by the rear wheels. Sounded like someone was beatin a piece of tubing under the coach. It comes and goes and for the life of me I can't find a thing!
My wife told it happens all the time - even in our other coach. So what's up???
It's a mystery to me. </div></BLOCKQUOTE>
Is the plumber's truck still in front of your house?
It could be what you mentioned, a piece of tubing from one of your holding tanks vibrating between the tank and coach floor.
