Hey Robin! I'm sorry to say that none of the Advent Air AC models are able to replace a Dometic Duo Therm like yours. What I recommend is completely replacing the system. Not only will this allow you to avoid any compatibility issues, it will allow you to upgrade to an AC unit with the new R32 refrigerant.
All of the old R410A units and their parts are being phased out. It would be a shame to swap just the AC only to find out you have to replace the whole system a short while later over something like an air distribution box or thermostat. Sticking with Advent Air you can choose from the following:
-Advent Air RV Air Conditioner System - Single Zone - 15,000 Btu - White - R32 # ADV92SR
-Advent Air RV Air Conditioner System - Manual - 15,000 Btu - White - R32 # ADV32SR
-Advent Air RV Air Conditioner System - Single Zone - 13,500 Btu - White - R32 # ADV95SR
-Advent Air RV Air Conditioner System - Manual - 13,500 Btu - White - R32 # ADV23SR
-Advent Air RV Air Conditioner System - Single Zone - 13,500 Btu - White - R32 # ADV87QR
-Advent Air RV Air Conditioner System - Single Zone - 15,500 Btu - White - R32 # ADV99QR
The single zone systems work with ducted and ductless setups and the manual works with ductless only. The newer # ADV87QR and # ADV99QR also have the option of adding a remote # ADV67QR. If you have any other questions feel free to reach out below.

Hey Robin, did you decide to go with one of the Advent Air systems for your replacement? I'm curious to know if the upgrade to the new R32 refrigerant worked out for you, as it could help others facing similar compatibility issues.
