I have heard this hissing, whining sound also. It is the low pressure LP being sucked out of the regulator. Some regulators do this, most don't. If you want to be sure, run the coach by a RV specialist, and have them take a listen. They may, but probably not, charge you a couple of bucks, but it will be worth it in peace of mind.
