Hello David, thanks for reaching out. It is possible to replace your Dometic AC, but all of the replacement option will involve replacing the entire AC system: rooftop unit, controller, distribution box and thermostat. With RV ACs going to the new R32 refrigerant, new units are not backwards compatible with older AC systems. That said, to replace your AC I recommend the following:

- Advent Air Low Profile RV Air Conditioner System - Single Zone - 15,000 Btu - White - R32 # ADV82SR

This comes with everything you need to replace/upgrade your AC system. You get the rooftop AC unit, distribution box, controller, wall thermostat and start capacitor. This will work with both ducted and ductless systems.
