Is any of your other 120 volt stuff working.......television, microwave, air-conditioner?
You MUST be plugged into some form of 110/120 volt shore power for the outlets to work. You might want to make sure your shore power breakers not tripped too.
If you are only on battery power (12 volt), the outlets will not work. However, Your lights, heater, etc. will still operate, as they work off of 12 volt.
You probably have more than one outlet too. Check any/all for a tripped gfci in all rooms. You might want to look around the kitchen area and there may be more than one in the bathroom.
