I also have Valid slides. I run the engine, but do not rev the engine. The engine running makes more air so the slide seals deflate faster.

Another reason to run the engine in travel mode.... when you are parked your coach may settle as small leaks deflate air bags. Running the engine in travel mode will level out the coach which means less stress on the bearings, rails, and slide motors.

My coach does not make a lot of noise at idle. Maybe you have a problem in the exhaust?
