Hi Jim,

If you're wanting to replace just the rooftop unit then you'll first want to remove the cover of your air distribution box to take a look at the controller. The controller will have a wire harness that hangs down from the rooftop unit and plugs into it with either a 6-pin or 9-pin connector (pictured below).

If you have a 6-pin connector then the Advent Air Replacement RV Air Conditioner # ACDOM150B would be a direct swap out of your current rooftop unit. If you have a 9-pin connector then you'll just need to use a wiring harness adapter like the # ACCOLKIT as well.

If you're looking to completely replace the entire system then I recommend going with the Furrion Chill HE RV Air Conditioner System # FR55PV instead. This will give you a new air distribution box and thermostat as well and you wouldn't have to worry about any compatibility issues since it would be all new equipment.
