No, he meant the fridge should be run through a dedicated fridge terminal on the split charge relay, or via a separate relay triggered off the same wire that triggers the split charge relay so that the fridge can ONLY come on when the engine is running. Reason = a normal camper fridge will draw 7 amps at a time and soon flatten either battery if the engine isn't running.
