Hey Brian! Yes, it is possible and which parts you need are going to depend on whether your 5th wheel trailer has a ducted or ductless system currently. I have listed the options below:
Ducted System - Furrion Chill Cube RV Air Conditioner w Air Distribution Box item # FR39TD
Ductless System - Furrion Chill Cube RV Air Conditioner w Air Distribution Box item # FR27TD
Please note that the new Furrion Chill Cube is not backwards compatible with any other system you currently have on your Keystone Cougar. This is due to the new R32 refrigerant that meets the 2025 EPA regulations. You will have to replace everything from the AC unit to the distribution box.
If you have a furnace or would like a thermostat you'll also need the Thermostat for Furrion Chill Cube Ducted RV Air Conditioners item # LC74DX.

Hey Brian, how did the swap to the Furrion Chill Cube go on your Keystone Cougar Sport? Were you able to match it up with the right ducted or ductless setup? Your update could make it easier for the next person planning the same upgrade.
