Question:
We have two units. Need to replace the bedroom unit on fifth wheel camper. It’s dometic on a 2015 Montana 3611RL It has wires coming from a small tin box in ceiling area of unit that looks like a phone jack. Does this new unit your selling have that jack wire? There’s nowhere to plug a six wire jack into on that upper area of camper. Tyia

Hey Dottie, unfortunately not all of the Duo Therm AC units have the needed 6 pin connector to use the Dometic wiring adapter of the Avent Air # ACDOM150 that you have. The previous answer page you mentioned should have mentioned that but what you'll need is the Air Distribution Box w/ Wall-Mounted Thermostat for Advent Air RV Air Conditioners # ACRG15 which is an air distribution box and wall thermostat you'll be able to use with your Advent air AC unit.
