12-Volt RV Refrigerators Truths

At a recent RV show, a factory representative told me that the 10 cu. ft., 12-volt refrigerator in his RV can operate 57 hours on one "small" 12-volt battery. I questioned how the 11-amp hour draw listed on the specification sticker inside the refrigerator could power it for 57 hours, via the 50-amp hour reserve of a standard RV lead acid deep-cycle battery.
