Question:
I am looking at the kit CM48RR but I can not find any info on the Coleman-Mach website, or any other website that lists information on that model number. They do have a model 38203-069 that is very similar. Is it possible that this is a typo? If not what are the differences between the two models listed above.

Expert Reply:
Hey Stephen. The Coleman-Mach Signature Mach 3 RV Air Conditioner System item # CM48RR is a complete AC system with a ductless air distribution box. The pn 38203-069 you referenced is just the AC unit, which only works on R32 systems.
The Coleman-Mach Signature Mach 3 RV Air Conditioner System item # CM48RR is a 13,500 btu AC with the new more efficient R32 refrigerant. The ductless air distribution box included is set up exclusively to be used in RV's that do not have vents.
If your RV has air vents you'll need the Coleman-Mach Signature Mach 3 item # CM35RR, which also includes a thermostat.
What kind of trailer or motorhome do you have?
