Hey Thaddeus! I'm sorry to hear your AC went bad but right now is a great time to upgrade. Companies are rolling out new R32 AC units to meet 2025 EPA regulations and old systems/parts are starting to disappear. Because of the differences in R32 refrigerant this does mean replacing the AC unit along with the air distribution box (ADB) but it isn't as difficult as it might sound.
For a replacement I recommend the new Furrion Chill Cube RV Air Conditioner. Since you have a ductless setup you need the # FR59TD (white) or # FR27TD (black). This system has an incredibly low power draw and will be extremely quiet compared to your old GE AC. The variable speed compressor means efficient cooling and less wear on the unit so it will last longer. In addition to the controls on the ADB it also comes with a remote that acts as a thermostat. If you need anything else feel free to reach out in the comments below.
