Two, if you do not have a battery in the coach the converter will hum louder. The design of the converter requires a deep cycle battery in good condition to be in the output circuit (as provided by Airstream) to operate properly. Not doing so will cause noise, both in the converter and the radio. It will eventually lead to accelerated failure of the furnace motor and the converter it's self.
