Hey Arron, thanks for the information! Your Coleman Mach 3 48208-9660 has the older 410a refrigerant in it so the Coleman-Mach Deluxe ChillGrill Air Distribution Box you were looking at, is not going to be compatible.
In 2025 the EPA mandated the new R32 refrigerant for RV AC's. The problem with all the new R32 components is they're not backwards compatible with any 401a units like your Coleman Mach 3. I do not have any air distribution boxes that are going to work with your AC system.
My only solution for you is to replace your entire AC with a newer more efficient R32 model. Our most comparable replacement options are the Coleman-Mach Signature Mach 3 RV Air Conditioner System item # CM23RR for ducted or item # CM38RR for a ductless setup.
What kind of RV or trailer do you have?
