residential refrigerator vs rv gas/electric refrigerator?

"If you boon docked would the batteries need to be charged daily?"

Yes, Oasisbob, or you will significantly reduce your house batteries' life. A generator is the quick, old fashioned answer but solar is the easiest, cheapest answer but I do have a small backup inverter...unused except for 4 five minute exercise session in the last 60 days of camping.
