Hi David; all of the AC units have switched over to the new R32 refrigerant this year so we do not have a direct replacement for your Dometic Duo-Therm. The parts aren't backwards compatible so a complete replacement is necessary. This also means it is a good idea to make the switch now so you don't end up having to replace the entire system later should your air distribution box or other parts fail.
For a replacement I recommend the new Furrion Chill Cube. This AC takes advantage of the R32 refrigerant and uses a variable speed compressor. This means it is incredibly efficient and quiet while delivering incredible cooling power. It also uses a remote which acts as the thermostat. The correct replacement will depend on your current setup. You can choose from the following:
-Furrion Chill Cube RV Air Conditioner w Air Distribution Box - Ductless - 18,000 Btu - Black # FR27TD
-Furrion Chill Cube RV Air Conditioner w Air Distribution Box - Ductless - 18,000 Btu - White # FR59TD
-Furrion Chill Cube RV Air Conditioner w Air Distribution Box - Ducted - 18,000 Btu - Black # FR39TD
-Furrion Chill Cube RV Air Conditioner w Air Distribution Box - Ducted - 18,000 Btu - White # FR99TD
-Furrion Chill Cube RV AC w/ ADB, Thermostat - Ducted - White # FR69TD (if you also have a furnace)
-Furrion Chill Cube RV AC w/ ADB, Thermostat - Ducted - Black # FR49TD (if you also have a furnace)
The models with a wall thermostat are designed for setups with a furnace. You can also use your existing thermostat to run the furnace separately if it has that capability.
