Yes, an excellent replacement for your Coleman Mach 8000 Series air conditioner will be the Furrion Chill HE RV Air Conditioner System - Single Zone - 15,000 Btu # FR55PV.
This will be a completely new set up for your RV, giving you an upgraded unit with an easy-to-use thermostat, and will work as either a ducted or ductless system.
