I bit the bullet and purchased a whole house stand-by generator. It's rated at 18 KW and runs off of propane. I have two propane tanks and plan on getting another, I'd like to have 2,000 gallons of propane when all is said and done. We live so far out in the sticks that it takes weeks sometimes to get electricity restored due to the weather. Keep in mind that gas stations can't pump fuel without electricity. I've driven over 50 miles looking for gasoline. When we finally found one with power, there was 10,000 cars lined up waiting to top off their cars and fill gas cans. Keep plenty of gasoline and 2 cycle oil around if this is what you want to do.
Warning! My dog has a gun and refuses to take his meds!
