So,
No power in bathroom
No power in kitchen
No power in basement? (there aren't any outlets in the underbelly)
No power in the rear of the trailer?
These are on at least 2, perhaps 3 different circuits. It sounds like you've lost 1 leg of your 2 power legs coming from the 50 amp receptacle on the power pedestal.
- Ensure the shore power cord is fully plugged and locked.
- If you have a volt meter, check the power pedestal for correct voltages.
- If you have generator prep, you have an automatic transfer switch. L2 may not be passing power.
- You could have a loose wire on the back side of the main circuit breaker panel.
