Question:
Looking at the Advent Air RV Air Conditioner - 13,500 Btu - White - R32 on your website for replacement on a 2003 Coachmen Somerset 5th Wheel, which connects to duct work on the camper. Will I need to replace the thermostat and wiring for this model to work?

Hey Bill. You won't need to replace the wiring but the Advent Air RV Air Conditioner item # ADV96SR has the new R32 refrigerant so it will not be backwards compatible with any of your existing components. You would also need to replace the thermostat and air distribution box. For this you'll want the Advent Air Low Profile RV Air Conditioner System item # ADV52SR.
Do you have a furnace in your 5th wheel trailer?
