Myself I would seriously consider buying a large YETI® ice chest, which will last the rest of your life, then your kid's and their kids. The unbelievably long retention of ice in a YETI will hold food for a week especially where you live. No gas, no flue, no controls, no ammonia - just ice it up and go. Use the refrigerator to hold non perishable items, extra clothes, booze, whatever. The appeal of a "99-year" lifespan to me is highly attractive. And no, the YETI is not inexpensive.
My ice chest retains fruit and vegetable crispness and freshness light-years better than even my $5,000 Viking home refrigerator or $3,000 Vestfrost 24 volt RV unit.
Something to chew on anyway... :)
