Question:
I am needing a new ac and interested in the furrion 18btu. I currently have a Dometic FJX3573MWHAS. I am wanting to replace the outside/inside and thermostat. Mine is a ducted unit. Can you send me which one I need and if you have a bundle.

Hey Hoot! Do you have a furnace as well? If so, you need the Furrion Chill Cube # FR69TD (white) or # FR49TD (black). This includes the AC unit, air distribution box, and the wall thermostat so you can still run your furnace along with the AC. If you don't have a furnace you won't need the wall thermostat anymore since it comes with a remote that acts as the thermostat. The version without the wall thermostat is the # FR99TD (white) or # FR39TD (black). These are all complete systems bundled together.
