We currently have a new Samsung 216 liters (7.63 cu. ft.) inverter refrigerator. Since we are moving out to the farm 30 kilometers (~18 miles) away from town, I am seriously looking at buying a chest type freezer, 300 liters (10.59 cu. ft.) capacity and possibly, another refrigerator. I am thinking along the lines of a 580 - 620 liters (20.48 - 21.9 cubic ft.) capacity refrigerator. This would be to limit shopping trips to the city. Family of 2, full-time, living on site. Good idea, or over thinking my self-sufficiency.
