Question:

I want to stay with Coleman-Mach, but I don’t need a 15K unit. I just want a 13.5K replacement for my midsized camper. Which parts should I be looking at?

Hey Rafael! I'd go with the Coleman-Mach Signature Mach 3 # CM97RR if you want the 13,500 Btu rooftop unit. Just keep in mind it’s the rooftop AC only, so you’ll need the correct air distribution box to complete the setup unless you already happen to have the modern R32 refrigerant. The new units aren't backwards compatible so you'd need to replace the other components if you have the older R410 refrigerant which got changed over a couple years ago.

For a ductless camper, use the Coleman-Mach Deluxe Air Distribution Box # CM46RR. For a ducted camper with ceiling vents, use the Coleman-Mach ChillGrill Air Distribution Box # CM36RR. You can also add the Coleman-Mach heater kit # CM96RR if you want light electric heat. Is your current camper ducted or ductless, Rafael?
