Hi Collin, welcome back! The most economical replacement is going to be from Advent Air. You will need a complete system since everything moved to R32 refrigerant.
If your upgraded thermostat is R32 compatible, or a smart thermostat that got a software update, you can potentially carry it over. Otherwise, you're going to be using the thermostat designed for the system since R32 electronics communicate differently.
You can choose from the following based on capacity and color:
-Advent Air RV Air Conditioner System - Single Zone - 13,500 Btu - White - R32 # ADV87QR
-Advent Air RV Air Conditioner System - Single Zone - 13,500 Btu - Black - R32 # ADV59QR
-Advent Air RV Air Conditioner System - Single Zone - 15,500 Btu - White - R32 # ADV99QR
-Advent Air RV Air Conditioner System - Single Zone - 15,500 Btu - Black - R32 # ADV69QR
These also have an optional Bluetooth remote # ADV67QR which is a nice additional feature.

Hey Robin, Thank you for the guidance. I have a 2004 Thir Mirage. The ac system went out. I updated the motor and thermostat but still was unable to get it to blow out any air. It turns on, but thats it. My thermostat model is dometic 50-142802-d. I dont think that it's compatible. My heater also stopped working as well. The last time it went out I replaced the sail switch and got it running again. It seems like everything is breaking down at the same time... any suggestions?
