Question:
I have a 2003 Fleetwood Discovery 38U motorhome with two rooftop ac units by Coleman mach 7000. Both units are controlled by a wall mount thermostat. What will be a direct replacement ac unit? Im wanting to just go ahead and replace both. Will I need a new thermostat because I dont think the original one works to well.

Hey Keith! I just got your questions so I'll address everything on this one. All of the replacement AC units have switched to the new R32 refrigerant so a complete replacement is necessary. This will include a wall thermostat so you don't have to worry about compatibility or if the existing one even works.
The GE AC you were looking at will work as a replacement for the Coleman. The correct system will depend on whether you have a ducted or ductless setup, the color, and if you want the heat pump. You can choose from the following:

-GE Appliances Deluxe Plus RV AC System w/ Heat Pump - Ducted - 15,000 Btu - White # GE85ZR
