RV air conditioner units unfortunately do not have the option to have their refrigerant levels recharged because the manufacturers close off the system instead of building in a port so you're looking at replacement. You can save a bit of money by just replacing the rooftop condenser unit instead of the entire system though. You'll just need to do a bit of investigative work to see what style connector your condenser unit has.
If you remove the cover to your air distribution box on the inside of the trailer you should see a a wiring harness hanging down from the condenser and plugging into your system's controller. This wire harness will have either a 6-pin or 9-pin connector. If you have a 6-pin connector then the Advent Air Replacement RV Air Conditioner # ACDOM135 you were looking at would be compatible. If you have a 9-pin then you would just also need to get an adapter # ACCOLKIT in order to plug-in the new unit.
