Question:
I have a 2008 Forrest river wildcat 5th wheel and need to replace the rooftop ac unit while reusing the inside components. It is ducted and a domestic duo therm brisk. I can’t find a model number on it either. Do you offer anything that is a direct replacement? The only number I found is in the attached photo on the lower shroud.

Hi Austin; all of the AC systems have moved to the new R32 refrigerant following the new 2025 EPA guidelines. These systems require complete replacement so you will need to swap out the air distribution box (ADB) and thermostat as well.
Even if that wasn't the case, we no longer recommend trading out just the AC unit since there have been too many compatibility issues. You wouldn't want to swap out the AC only to have it burn up your ADB and you end up needing a complete replacement because the old parts are no longer available.
Assuming you want and Advent Air system you can choose from the following:
-Advent Air RV Air Conditioner System - Manual - 15,000 Btu - White - R32 # ADV32SR or # ADV42SR (Black)
-Advent Air RV Air Conditioner System - Manual - 13,500 Btu - White - R32 # ADV23SR or # ADV75SR (Black)
-Advent Air RV Air Conditioner System - Single Zone - 15,000 Btu - White - R32 # ADV92SR or # ADV62SR (Black)
-Advent Air RV Air Conditioner System - Single Zone - 13,500 Btu - White - R32 # ADV95SR or # ADV52SR (Black)
The manual systems are for ductless setups and the single zone works with both ducted and ductless.
Any trips planned with your 5th wheel this fall?

Hi Austin, did you decide on an Advent Air system for your 5th wheel? I'm curious to know how it worked out for you, as it could help others facing similar replacement needs.
