it could also be your ATS(auto transfer switch) with a loose wire.... find it, open it up while no shore power or generator, and check each screw connection.
you can also check the connections within your Main Panel, for the main wire coming into each breaker...
I doubt it was any 'power surge', as any RV is built to receive the power no matter when it 'occurs', whether the breaker is already 'on', or when you 'flip it on', etc.
