Since you are using shore power, you can replace your Coleman with an Advent 15,000 Btu unit and just need the wiring adapter. I really like the low profile units so I recommend going that route, and you can choose from either White or Black in color:
- White: Advent Air Low Profile RV Air Conditioner # ADV29FR
- Black: Advent Air Low Profile RV Air Conditioner # ADV56FR
- Adapter Wiring Kit for Advent Air RV Air Conditioners # ACCOLKIT view full answer...
