Question:
I would like to replace the AC in my 2021 Wildwood 171RBXL that currently has a non-ducted Coleman Mach III 13,500BTU. I am looking for a Furrion Chill Cube that might be a a in replacement. The Coleman when it was working at 13,500 BTU was more than enough to cool the RV in the summer, but Id like something now more efficient. Im hoping you can recommend something quickly since I have a trip planned in a couple of weeks.

Hey Reid! Since you have a ductless setup you need one of 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
The Chill Cube is definitely going to be more efficient than your existing AC system. It has more power but it won't be too much since it uses a variable speed compressor. This includes the air distribution box and a remote which also acts as the thermostat.
Where are you headed on your trip?
