Properly done, the RV will have a 30A breaker in its own panel. so even though the outside panel is 50A, your still protecting your own wiring with a 30A breaker.
Agreed. Regarding the camper's wiring on the load side of the camper's electrical box, this discussion is irrelevant. But the wire between the camper's internal box and the shore power breaker should be sized for the breaker feeding it, not for the load it serves. You can save weight if you want. But if the OP is rewiring the camper anyway, and anticipates camping where only 50 amp service is available, why not be safe?
Though your point is valid, I don't completely agree with it. What about a small appliance in your house? It has a cord sized for itself but plugs into 15 or 20A receptacle backed by a 15 or 20A breaker. The appliance wiring likely going to handle 20A but it's not a problem to use it that way.
With the camper supply cord being the only thing "exposed" to 50A, I don't see any practical way it can draw between 30A and 50A for any length of time. Too much load in the camper will trip its 30A main. A direct short within the cord will trip the pedestal 50A breaker, even with 30A-sized wire.
