Some coaches have more than one GFI outlet so you may have one that is tripped that feeds the bedroom. Sometimes these GFI's are well hidden. They may be in the basement or on the side of a bath cabinet or even the side of a bedroom cabinet.
Also look at your inverter and see if ONE of the circuit breakers has tripped. My inverter has two outputs and I can lose power on some of my outlets but not all of them if one trips. These circuit breakers are located right on the inverter itself and are before your circuit breakers in your main electrical panel.
The AC problem might be a bearing that is starting to fail in the fan.
