Hey Robert, you can basically use any RV AC unit available to replace your Coleman Mach but since there was a refrigerant law change in January of 2025 you would need to replace the entire unit including a new thermostat and air box as all of the components now are different. So the Advent Air part # ADV92SR would be a great option for this. How do you like your current Mach 1?
