On ours anyway, for the inverter, there is a AC breaker under the bed for the inverter and also a on/off and small push button breaker on the inverter itself. have had our breaker on the inverter trip a few times.
if you have a night light, just take it and check each outlet in the coach and see if any of you outlets are not working, then like tmmar said could be a GFI outlet popped. on ours there are you outlets that are GFI protected, one in kitchen and one in bath.
