Hey Clyde! The Furrion Chill Cube will be a really nice upgrade so I highly recommend going that route for replacement. This unit is super quiet and incredibly efficient with a lot of cooling power. This will be a complete replacement since everything has switched over to the new R32 refrigerant. The correct system depends on whether you have a ducted or ductless setup and if you do or do not have a furnace. 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/ Air Distribution Box, Thermostat - Ducted # FR69TD (if you have a furnace)

-Furrion Chill Cube RV AC w/ Air Distribution Box, Thermostat - Ducted # FR49TD (if you have a furnace)

The models for setups with a furnace include a wall thermostat since the remote can only operate the AC. If your existing thermostat can run the furnace on its own (some require the controller in the AC for operation) you can forgo the Furrion wall thermostat and keep the two systems separate.

What kind of trailer do you have? If you have any additional questions on the Chill Cube or other AC units feel free to reply below.

I have a 2008 Fleetwood with dual ac units “Coleman Mach” and heat controlled by the same thermostat.ls there a plug and play option for this setup?

@Clyde unless you're replacing it with the same manufacturer/model we don't recommend that anymore. There have been a lot of compatibility issues across brands and you really don't want to be up there with the AC unit pulled off, install the new one, and find out nothing works. I also recommend making the switch to a new R32 AC because all of the old R410A parts are no longer being manufactured and quickly disappearing from inventory everywhere. The Chill Cube is definitely worth the extra installation steps and it won't be a significant amount of additional work to swap out the ADB and thermostat.
