Suburban, Attwood, or Hydroflame make the furnace unit ... Dometic was and is the brand of control thermostat you have on your wall for both A/C and heat. Like I mentioned, 10 years ago we all had a wall thermostat and remote that was common on about any Montana. You either lived with about a 10 degree temp swing with the A/C and furnace fighting each other or got Dometic to swap out the Dual Climate Control with the CCC control which was waaayyyyy better. Here's a shot of the remote.
