Twenty five of the 20 pound propane tanks (bought at yard sales and refilled myself) and about 50 gallons of regular gasoline. I have additional empty storage space for gasoline when necessary.
FYI, One twenty pound propane tank is reported to be able to provide 30 days of cooking for a family of four....
Whoa, dude, you are seriously prepped!
When the SHTF, I am coming to Mobile to find you.
I will be bringing 10-20 close friends and relatives, so be prepared!
The question is can you defend your position from the roving bands of takers? Unless you are very rural and use land/water obstacles as a barrier you will be overrun.
It won't. I use 20 lb propane tanks here to cook for one. Range only. I use an electric oven. 20 lbs of propane lasts one person about a month. I also use it to heat water to wash dishes since I haven't had hot running water in over 8 years.
I would knock about 5% of the time off per person I added to the household. So if I added 2 people, I'd knock 3 days off a 30 day supply of propane (20 lbs for me.)
That's my real usage for over 3 years. I won't cook on an electric range if I can avoid it.
