I have a 11 year old 6 cubic foot Dometic RM2652, I don't think it is as efficient as day one but it will use close to 20lbs a week in 90f + days.

There's approximately 91,500 btu's in a gallon of propane. Using as an example, a 12 cu/ft Norcold refrigerator that burns 2400 btu/hr.

A 20 pound propane tank should hold 4.7 gallons, so it should run the fridge for about 23.5 days.
