Being that we have a 5th wheel where there is 19.7 feet between the fuel input and the refrigerator, I feel very safe about running with the refrigerator on without imposing any safety hazard to myself or any other person.
Our size also prevents the refrigerator from being close to other pumps, for multiple reasons, removing the hazard from other people.
When refueling a smaller RV, a class C or any RV where the fuel input and the refrigerator are within a few feet, sure turn the refrigerator off. Much faster to reach the refrigerator in a class B or class C than going to the steps of getting in a 5th wheel.
