When on shore power or generator power, everything will work.
When not, only 12v items will work. So no a/c, no microwave, no outlets, no tv(unless it's a 12v tv), no heated mattresses.
If 12v items aren't working either, you probably tripped the 12v resettable circuit breaker that's tucked along the A-frame. It has a tiny black reset button you push.
By the way, Welcome to FRF. I used to live in Camarillo.
