Think of it this way: If you have wiring in your house that will support a 15a load (14ga), and you connect that to a 20a breaker (intended for 12 ga wire), what will happen if you overload that 15a wiring? The breaker won't trip before the wires melt and will start a fire. In this case, unless you have a 30a breaker/surge protector, the wiring in the camper will be toast before it trips that 50a breaker/surge protector. Kind of defeats the purpose of a surge protector doesn't it?
