First if you have an electric water heater. TURN IT OFF, likewise the do not use the microwave (use Propane to heat water)
The Energy Management system may be shedding the AC units.
in a dual A/C 30 amp rig there is, somewhere a switch.. It is usually a 3 way (Front/Rear/Both) and must be set properly.. Front one works, Rear the other works Both the manager takes over.
Generator overrides this
NOTE: one of the circuit breakers on the generator may feed the REAR A/C. both when using generator AND when using shore power. If this breaker is tripped the rear A/C will not work.
note also that Onan breakers do not have a "Tripped" position, it's on and off, if it trips it moves all the way to off. (in many cases)
