Question:
Hello, I have a 2021 Redwood 4150RD I would like to replace my 3 ducted air conditioners. I do not care about power usage, or noise however I do want for the units I replace them with to be the coldest air with the highest airflow coming out of the vents. Would you be able to assist with finding these units to fit my fifth wheel?

Hey Korry! The system with the coldest air and highest air flow is the Furrion Chill Cube. This system has an incredibly high 18,000 Btu cooling capacity. It also uses a variable speed compressor for efficient cooling. I know you're not looking for it specifically but, on top of the cooling power it is incredibly quiet with a really low overall power draw. Since you have a ducted system 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/ Air Distribution Box, Thermostat - Ducted - White # FR69TD (if you have a furnace)
-Furrion Chill Cube RV AC w/ Air Distribution Box, Thermostat - Ducted - Black # FR49TD (if you have a furnace)
The second two options come with a wall thermostat which will be required to operate a furnace. You will only need one wall thermostat for the furnace so you can get the systems without it for the other two. The AC itself runs off of a remote which acts as the thermostat or the controls on the ADB.
Any big plans with your 5th wheel this summer?

Is there a ducted low profile version of the furrion chill cube yet? I’d like to replace all three of my GE profiles on my toy hauler but the regular chill cube puts me over on height. I saw a low profile furrion at 13,500 btu but I don’t think it’s the chill cube.
