Since we don't carry the Coleman brand I can't really speak to their quality but I can say that if you're wanting to only replace the rooftop units that the Advent Air Replacement RV Air Conditioner for Dometic Setup w/ Start Capacitor - 15,000 Btu # ACDOM150B would be a great option for you.

This particular unit comes with a wiring harness compatible with Dometic branded AC units so that installation is plug and play. The included start capacitor stores energy to help start the unit when shore power or generator power isn't enough. This helps prolong the life of the unit since it won't have to run as hard to start.
