Question:
Hi I have a 2015 coach house platinum 2 241xl and this says that this unit is compatible with my rig. Will I need a distribution box and thermostat with this unit? Will it be just plug and play so to speak? Is the wiring harness the same. I need to replace just the unit what other parts will I need to complete the replacement?

Hey Jim, the part number you referenced is just the top unit and would not be compatible with any lower vent assembly you have already. So what you'd need is the part # ADV92SR which comes with a wall thermostat and a lower vent assembly that is all compatible with each other.
At one point we all though that there was some mix and matching you could do with RV AC units between the upper and lower units but we found out that it unfortunately doesn't work out.

Hey Jim, did the Advent Air system with the wall thermostat and lower vent assembly work out for your Coach House? I'm curious because it could help others in a similar situation.
