We make sure we properly store what we have in a pantry that is cool and dry and kept very very clean . Case lots are marked with purchase date and expiration date. We have racks for canned goods that roll the oldest can to the front for use first priority.
Use food saver vacuum bag system to pack family size portions to keep all from going bad at once of dry goods like pastas, rice, pintos etc ......
We have a RAIS wood stove we use for heating that has a baking chamber above the firebox. We can make breads or a dutch oven for making stews etc . About a years supply of basics is on hand with canned goods, meat, fish and fowl from hunting and fishing and canned goods and frozen veggies from the gardens .
Our two trucks are diesel cummins dodges and I have a FJ80 with a cummins in it as well. Each of the trucks have 150 gal bed tanks with aftermarket 55 gal aero tanks . The Landcruiser FJ80 has a 34 OEM and 38 gal Old man Emu aux tank. All are kept full so if we stopped having to drive to and from work tomorrow we have fuel for short trips for a year or more IMO.
My next purchase is a KLR650D aka diesel motorcycle. USMC has been using em for a while and they work fine for utility purposes. We have two KLR650 mo-gas bikes and they are fine but our “bulk” sources of fuel are diesel in the trucks bed tanks.
Point being this is not something we have just started doing.....this is a lifestyle we have practiced for decades due our desire to be self reliant of all about us turns to crap due a lay off, illness etc ......
Prior military IMO is the best source on how to handle youself when shtf. Been my experience that most prepare first for the worst and if that don't happen, it's a bonus.
