Hey Lonnie, thanks for reaching out!
I recommend replacing your old Duo-Therm AC unit with a Dometic Penguin II Low Profile air conditioner because it will plug right into your existing setup and it has the lower 12-13/16" tall profile so it gives you more of a sleek look.
I'm not sure what the Btu rating is for your current AC system but you'll need part # DMC36ZR for a 13.5K Btu rating or the part # DMC33ZR for a 15K Btu rating.

Hey Lonnie, how did the replacement go with the Dometic Penguin II on your Coachmen Concord? It’d be great to hear which Btu rating you went with and how it’s performing so far. Your update could make it easier for the next person with the same setup.
