The camper's breaker panel is a subpanel because the wiring to it includes concealed (in-wall) wiring within the camper structure that is inaccessible by the occupant. Therefore, the NEC requires that the wiring between a main panel (campground pedestal) and a subpanel (camper breaker panel) be rated to carry the amperage of the main panel's breaker. So if your camper is built for 30 amps, its internal wiring to its panel is only rated for 30 amps (not 50 amps). So the issue at hand are not the circuits protected by the 30 amp camper panel, it is a short or other wiring issue (loose connections being a common one) in the internal concealed wiring prior to the camper's panel.

It doesn't matter that you have a 30 amp cord plugged into a 50 pedestal (via the proper cord adapter) going into a 30 amp coach... because the main breaker in the coach will prevent a draw of more than 30 amps.
If you are concerned about a short in the cordset between the 50 amp pedestal breaker and the coach's 30 amp breaker, that is somewhat valid... but a non-issue in real-life. The only load that would occur there would be from a dead-short in a damaged cord. In that case, the 50 amp breaker in the pedestal would still trip.
You do realize that 30-50 cord adapters have been around for a LONG time and in use by a ton of campers. This is such a non-issue.
