Not sure about your question.
But I understand that; RV 30 amp, is not the same as household 30 amp service, even though the same pattern plug connector.
RV only one prong gets a 110V leg with 30 amp single pole breaker, where household gets two separate 110V legs with a double pole 30 amp breaker.
I believe RV 50 amp is wired the same as household 50 amp.
Having two 110 volt legs protected with a 50 amp dbl pole breaker.
So there could be a problem trying to run your rig if an adapter runs both to the single pole 30 amp, thus the amps drawn scenario as Chuck and Mary Ann mentioned.
