Hello William,

Thanks for writing in!

The Coleman-Mach Deluxe ChillGrill # CM66RR is designed for the newer Coleman-Mach R32 non-ducted air conditioners. Since Coleman transitioned from R410A to R32, the # CM66RR is not backwards compatible with the older R410A setup.

With your 2026 Coachmen Pixel 1.8RB being right around that changeover, I don't want to assume which version of the Mach 10 NDQ Coachmen installed. We'll need to verify that your rooftop unit is the R32 version before I can say for sure that the # CM66RR will work.

The easiest way to do that is to get the model number off the sticker on your Coleman-Mach unit. If you're unsure where to find it, please feel free to send me a picture of the model number sticker by responding directly to the email you receive. I'm happy to take a look and confirm whether the # CM66RR is the right airbox for you.

Are you replacing the airbox because something happened to the original, or are you looking to upgrade the setup before your next great adventure?

My current AC pushes out out the sides, directly into the bathroom and storage over the driving compartment, was looking for a way to deflect the AC air down, the CM66RR has the moveable vents, was thinking this might be a good replacement since I have not been able to find any other ways to deflect AC air. My manual for the AC provide the following: Model No. 35203-0793 Serial No. 260048142 Mach 10 13.5 Non-Ducted Quiet A/C Thanks!

@WilliamG Good Morning William, Thanks for getting back to me with that model number! That was exactly what I needed. Your Coleman-Mach model 35203-0793 is the newer R32 Mach 10 NDQ, so the Coleman-Mach Deluxe ChillGrill # CM66RR will work with your air conditioner. Now that I understand what you're trying to accomplish, I think this will be a great upgrade for you. The adjustable vents on the # CM66RR will let you direct the airflow where you actually want it instead of having so much of that cold air blowing toward the bathroom and storage area. While you have the old airbox down, I would also take a look around the ceiling opening. If you find any gaps or old HVAC tape that needs to be replaced, the LaSalle Bristol Aluminum HVAC Tape # UT83MR is great to have on hand. You can use it to seal those areas before installing the new airbox, which helps keep the conditioned air from escaping into the ceiling instead of coming out where you want it.
