I might have missed this part of the discussion, but I go months w/o using much propane.  How long are you using the fuel before you run out on a trip? Before my recent DV trip, I pulled into my propane place & it only took 1.3 gallons after a week at Burning Man, & 3 weekend camping trips after that, w/ one trip including running my 3000 btu catalytic heater for part of a day. Now I will admit I don't use the propane for my fridge, but do use it for cooking & heat.
