Question:
I have a DuoTherm model 59516.331 ac condenser unit I took off another trailer and looking for a air distribution kit to fit this unit. Is it still available or will the newer model work? Thanks for your time. Been a customer for a long time.

Hello Kevin, thanks for reaching out. I am sorry to say we do not offer an air distribution box to go with that. Main reason being what you have is an older AC unit that uses the now discontinued r410a refrigerant. The new RV AC units and distribution boxes now use R32 refrigerant. The new distribution boxes are not backwards compatible with old AC units. So the only solution here would be for you to either find an old Duo Therm distribution box, or to use a new R32 AC unit and distribution box.
