I've never heard an RV AC that was "nice and quiet". Even the Whisper Quiet units make quite a bit of noise and even a ducted 2nd AC unit will still be pretty loud. How loud is the main AC?

As far as a 2nd AC I would keep the brands the same IMO. When I added a 2nd AC in my last trailer I went with the Dometic Penguin 13.5k. It was non ducted but they have ducted options as I recall. As far as InCommand I don't know. Is the existing thermostat a dual zone capable of adding the 2nd AC or does it require its own thermostat?
