Hey Paul! For a replacement AC on your 2017 Grand Design Reflection 337RLS I recommend the Furrion Chill Cube. The Chill Cube is the latest AC from Furrion and it is really impressive. This takes advantage of the new R32 refrigerant and uses a variable speed compressor for unmatched cooling power and efficiency. It is also unbelievably quiet. It looks like you have a ducted system so you can choose from the following:
-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/ ADB, Thermostat - Ducted - White # FR69TD (if you also have a furnace)
-Furrion Chill Cube RV AC w/ ADB, Thermostat - Ducted - Black # FR49TD (if you also have a furnace)
The two models listed for a setup with a furnace have a wall thermostat. If you want the AC system to work with the furnace you will need the additional thermostat. You can also use your existing Dometic thermostat if it is capable of running the furnace on its own. The Chill Cube will operate independently using the remote or the the controls on the ADB.
Any big plans with your Reflection this summer?

Thanks for your assistance. It actually was about two days late as I went with a eco cool. Hope it doesn’t come back to bite me
