OK looked at your wiring diagram. You're saying all the outlets highlighted are the dead ones? My coach outlet locations match the diagram except in the bedroom (I have a slideout too). It looks like all of them are on the same breaker. Breakers can fail too without obvious signs. Switch out that circuit's breaker with another one and see if that kills a different circuit (or at least makes your outlets live again).
