1st you have 2 circuits of outlets inside your RV. A General circuit and a GFI circuit. The GFI circuit consists of 5 or 6 outlets within 6' of a water supply to include an outside outlet and any outlet with ground-level access in a storage area. The General circuit will be the remaining outlets. Bedroom, living area. etc. It is unlikely that both will be out at the same time.
Check the 120-volt circuit breakers. reset them by turning the breakers hard off then hard on. Reset the GFI circuit in the bathroom. Fuses are 12 volts. Not your problem.
