The Atwood Air Command Rooftop RV Air Conditioner w/ Heat Pump # AT15028-22 includes a vent assembly and thermostat that it would need to use when installing in your RV. You would not be able to reuse the Coleman vent and thermostat assembly. This kit does come with everything needed to complete the install though so nothing else would be needed. It does have the heat pump like you are wanting as well. view full answer...
