The coach batteries is what runs most of the 12 volt systems in your rig.
I would say you should start by cycling the battery disconnect. Turn it to store or off, then turn it back on. Have a 12 volt light on. See if the light becomes brighter when turning system on.
You could have a bad converter, reverse polarity fuses are blown or the main fuse from the converter is blown in the 12 volt DC distribution panel.
Verify that there is 120 volts to the receptacle or input to the converter. No 120 volt, reset all 120 volt circuit breakers, don't just look at them. Turn all breakers off applying light pressure toward off. Then turn on main breaker. Then turn on branch breakers one at a time. Give the system 10-15 seconds between branch breakers.
