Approaching your dilemma from an entirely different point of view---I completely agree with Ski in NC (who posted previously). SIMPLIFY YOUR LIFE! When you're on the hook for extended periods...shut down that Norcold and use old fashioned ice in a high quality cooler (Yeti or similar) for only those items that absolutely need refrigeration. Several reasons: (1) It's easy, (2) It's cheap, (3) It's foolproof. (4) Beer always tastes colder when you dig it out of an ice chest. And think of all the money you spend running the generator to keep junk cool, a lot of which doesn't have to be refrigerated at all (eggs, butter, cheese, vegies, etc.). You'd spend far less money on ice than paying the fuel tab to keep your bologna in a power-hungry fridge!
