In almost any situation, propane is going to be your best answer.
Being in Mo., you can pick up a Warm Morning LP stove at almost any farm sale. If you need to circulate the heat, put a Sterling engine with fan on top of the stove, no electricity needed.
Get a propane water heater, cheaper to run than electric, and more effecient.
An on-demand water heater saves gas, and never runs out of hot water. A Poloma 55, starts with a D cell battery, or a pilot light.
A few propane lights, like a Humphries, gives you great room and area lighting.
A propane kitchen stove and a gas clothes drier, and you don't need electricity for much at all, however, a porpane conversion kit on your generator will make it run longer, cleaner, and you can still change it back to gas anytime you want.
Watch for Servel or Dometic refrigerators and freezers for sale, they run off propane, and quite economically, too.
I buy propane tractors, because they are cheaper to buy, last longer, and the fuel doen't go bad.
I have a 1000 gallon tank for the house, and a 500 gallon tank for the barn, and have the hose kit mounted to fill vehicles, 100 and 20 lb. cylinders, and the little brass adapter to fill 1 lb. tanks.
The 100 lb. tanks run tank heaters for livestock, and the swimming pool heater. If you have a propane furnace, a little 20 lb. cylinder will fuel it all night long in an emergency. The line on your tank regulator screws right in.
