Welcome to iRV2.
Sorry you're here with problems .
There is probably a GFIC outlet in line with the two dead outlets that needs to be reset , it might be in the bathroom . Unlike GFIC outlets in a house; in RVs the GFICs are wired to protect other outlets.
All my fifth wheels had a combination power box , with 12 volt fuses , 120 volt circuit breakers and the converter/charger in the back . Look for a brown metal cover with vents in the front.
