Jessica, you can use the Furrion Chill HE Replacement RV Air Conditioner for Coleman Setup # FR82PV to replace your current Dometic Duo Therm AC.

This AC has a simple bolt on install, comes with a 9 pin to 6 pin wiring harness to work with your Coleman setup so you can use your current air distribution box, and is compatible with ducted and ductless setups.

Hey Jessica, how did the swap go with the Furrion Chill HE air conditioner for your Duo-Therm setup? It sounds like the wiring harness made the change pretty simple. Your feedback could really help others planning a similar replacement.
