Hey Ron, it wouldn't work because that is an older style air box and starting in 2025 the RV AC units had to switch to a different refrigerant. This means the lower vent assemblies had to change as well.
This means you'd need a current kit like the part # ADV25SR which has an air box that is compatible with the new refrigerants.
