I solved the fuel problem in my IL days by having a generac natural gas fired 10KW beast installed with automated switching. Had old folks on board who could not tolerate loss of central heat. Now I am less affluent, more mobile, and living im Palm Beach, so i acquired a portable 5KW gasoline machine. Gasoline storage is dangerous and tedious in the amounts necessary for a prolonged outage. I think I will store a modest amount, with a layered defensive plan involving ice chests and camp stoves, charcoal grill and canned food. I worked daily for three years with 5 high-cost propane Onan RV generators, and concluded that propane-fired generators were very clean and convenient to service during their frequent, complex breakdowns.
