thanks for getting back to me. My rig is a 87 fleetwood southwind 24 ft. The a/c is a dometic . the thermstat control in the bedroom is Suburban, but there is no indication on it that it is for a/c, but maybe heater, because it says "solid state ignition " on it. There is an empty hole above the side door on the cabinet with a pair of 110 wires capped off and it looks like it might have had a wall switch there. could that be the on/off switch for the a/c? would I be able to check with a multimeter? the breaker for the a/c is definitely on the main breaker control panel. Also, I understand that there are 2 ways for the a/c to get power: generator and shore. I have a 30 amp plug with a 15 amp adapter already on it. if I have all my ducks in a row so to speek, should the a/c be able to run off that?
