[Lewis and Clark]

Hello Art, Not sure where to locate a 110 breaker other than your breaker board in the rear of the coach(bedroom or rear closet) but don't you have a 12 volt air pump that runs the toliet and pocket doors when you are dry camping and not running the gEnny. If not maybe your air compressor is powered through your inverter and if so, check to make sure that it is functioning correctly. Good luck wish I could be more help. I am sure some of the other guys with more knowledge will also post with some help.
