Thank you for those photos, and I'll do my best to try and make things a little clearer for you. Essentially, what you need to do to determine if the Advent AC is compatible with your current Dometic Duo Therm set up is unhook the wiring from from the photo you added and take a look at the connector. What it needs to look like is the 6-pin connector in the below photo. If it has that same connector, you can replace your AC with either of the 13,500 Btu Advent options:

- White: Advent Air Replacement RV Air Conditioner for Dometic Setup # ACDOM135

- Black: Advent Air Replacement RV Air Conditioner for Dometic Setup # ACDOM135B

This will plug into your current wiring and work with your current thermostat.
