Question:
I own a 2022 Jayco Pinnacle 37MDQS fifth wheel trailer. It is equipped from the factory with two Coleman Mach A/C units one for the rear living area which also can function as a heat pump and the other for the front bedroom area. Both are ducted units. They are controlled independently two separate zones via a BMPro JayCommand touchscreen controller. The trailer is factory-prepped for a 3rd A/C unit, which would replace an existing Maxx Air vent fan in the main living area. For this 3rd unit I would like to purchase the Coleman Mach Signature Ducted 15k BTU unit CM89RR and the Coleman Mach ChillGrill Ducted Distribution Box CM36RR. Can you confirm whether these two products are compatible with my existing system?

Hey Gary, the third AC unit prep kit you have would be compatible with the Coleman-Mach Signature Mach 15 # CM89RR and air distribution box # CM36RR as long as its a ducted setup. If the prep kit has no ducting then there wouldn't be a way to integrate the system into your current control system and it would be designed for an independent air box like the part # CM66RR.
Let me know more details on your setup though and I can see if there's a better solution.

Hey Gary, did you get a chance to check whether your third A/C prep kit includes ducting for the main living area? Once you know that, it’ll be easier to confirm if the Signature Mach 15 and ChillGrill box will tie into your current control system. Let me know what you find—I can help narrow it down from there.
