Just to be clear, you have plugged your 50 amp RV into a 30 amp shore power plug. The shore power breaker is now tripping where it didn't before. Correct?

A 30 amp service is considerably less than 50 amp. The AC can take a significant part of those 30 amp. I assuming you have energy consumers like the hot water heater on Propane. If you have been fine for three years and nothing has changed in your usage, then I would conclude the 30 amp breaker on the shore power is getting weak after repeated trips.
