Hey Suzette! We no longer recommend swapping out an AC unit like the Advent Air for Dometic. The issue is most of the time they don't end up being compatible, even if the 6-pin connector matches. Even if you got another Dometic we can't always guarantee compatibility unless it is the same model.
Since AC units are all switching to the new R32 refrigerant I recommend getting the Advent Air RV Air Conditioner System # ADV23SR or # ADV95SR. The # ADV23SR has a manual air distribution box (ADB) and works with ductless setups. The # ADV95SR uses a wall thermostat and is compatible with both ducted and ductless setups. Both include a start capacitor and have the option to add a heat strip # ADV34QR. If you have any other questions feel free to reply below.
