Question:
I have a 2006 Newmar Kountrystar 39 ft with 2 dometic duo therm with heat pump. What ac unit do you recommend for a plug and play replacement? I need both units.

Hey James, welcome back! Since everything switched to R32 refrigerant there are no plug and play replacements available. The only option is to replace the entire system. If you're fine without the heat pump, you can still use an Advent Air like the old one you were looking at.
We have the manual ADB that works with ductless setups, or the model with the single zone thermostat that works with ducted and ductless setups. You can choose from the following:
-Advent Air RV Air Conditioner System - Manual - 15,000 Btu - White - R32 # ADV32SR or # ADV42SR (Black)
-Advent Air RV Air Conditioner System - Manual - 13,500 Btu - White - R32 # ADV23SR or # ADV75SR (Black)
-Advent Air RV AC System - Single Zone - 15,000 Btu - White - R32 # ADV92SR or # ADV62SR (Black)
-Advent Air RV AC System - Single Zone - 13,500 Btu - White - R32 # ADV95SR or # ADV52SR (Black)
If you want supplemental heating, a heat strip is available separately # ADV34QR.
Is the Kountrystar a different project you're working on since the Chill Cube installation?
