Nothing will beat the efficiency of a fridge running on propane.

Do you know by any chance how much propane would my 4.3cu.ft. fridge use, let say in a week of boondocking?
A small 1.7 to 1.9 cu ft manual light fridge like a Norcold 323 consumes ~ 625 BTU/Hr so it's seems reasonable that a fridge twice that size would consume twice as much gas, somewhat less if it's a DSI fridge that only runs the burner as necessary. Since yours is a 4.3 cu ft let's call it 1500 BTU/Hr x 24 hrs = 36,000 BTU/Day x 7 days = 252,000 BTU/Week. A 20 lb tank of propane is worth ~ 431,000 BTU, which is sufficient to run that fridge nearly 2 weeks, longer if it's a DSI fridge that doesn't run the burner 24/7.
