Question:

How is the hot air from the unit ducted out of the rv

Hey Ron! Great question.

The Coleman-Mach Underbunk AC # CM62RR is just the main unit, so it won’t include the ducting or venting components needed to move the air.

To actually route the hot air out and direct the cold air where you want it, you’ll need to pair it with the accessory kit # CM72RR. That kit includes the ducting and vents that handle both the intake and exhaust, so everything is properly routed outside and into the living space where needed.

If you’d rather not piece it together, we also have an all-in-one option, part # CM82RR, which includes both the AC unit and the accessory kit.

What camper are you installing the AC in?
