Hi Aaron, welcome back! Since your Coleman-Mach is an old R410A unit you will have to replace the entire system. Everything switched to R32 refrigerant in 2025 because of the EPA regulations, and the new systems don't work with parts from old setups.
For a replacement I recommend the Furrion Chill Cube. This system really takes advantage of R32 capabilities with a variable speed compressor. That means it is incredibly efficient and quiet, while delivering the most cooling power out there right now. Your 2018 Jayco Precept has a ducted setup so you need one of the following:
-Furrion Chill Cube RV Air Conditioner w Air Distribution Box - Ducted - 18,000 Btu - Black # FR39TD
-Furrion Chill Cube RV Air Conditioner w Air Distribution Box - Ducted - 18,000 Btu - White # FR99TD
Both of these come with the AC unit, air distribution box, and a remote which acts as the thermostat. You can use your existing wall thermostat to run your furnace separately. If you change your mind on the heat pump they do have a heat pump model coming out as well, you can choose from the following:
-Furrion Variable Speed Chill Cube RV Air Conditioner w/ Heat Pump - Ducted - 18K Btu - White - R32 # FR67TQ
-Furrion Variable Speed Chill Cube RV Air Conditioner w/ Heat Pump - Ducted - 18K Btu - Black - R32 # FR97TQ

The furrion chill cube is much more efficient than conventional RV air conditioners. I camped in hot weather a few times last summer and found the chill cube will cool the RV faster and it is quiet. I am really happy with it on my RV. Hope this helps anyone looking to make the swap.
