You can get these kind of "buckets", that make it easier to stack and store: https://www.amazon.com/Gallon-...uare+5+gallon+bucket NOTE - I'm not saying buy THESE exact ones....they're expensive, I'm just using these as an example
Good combination of Mylar bags and oxygen absorbers: https://www.amazon.com/1-Gallo...torage+bags+for+food
Subdivide the bulk food into 1 gallon bags. Why? That way you are only exposing a "gallon" of rice/beans/flour/sugar/etc. instead of 3 gallons, or 5 gallons. You are only opening what you NEED at the time, leaving everything still sealed/protected. Also, if you "botched" the sealing process on ONE gallon, you only lose that bit of food, if it was botched on a FIVE gallon bag, that's a LOT more food you just lost.
We supplement the above bulk rice and beans etc., with freeze dried meats. Rice and beans every day will start getting old without something else (like meat) to improve it. We also bought a bunch of BULK herbs and seasonings, to make the food taste better. Remember, at one time in history, SALT was worth it's weight in GOLD. Oatmeal is another good BULK item, along with various flours.
I look at everything with a eye to "being mobile" (what is easy to carry/prepare/eat), the first 30-90 days (lots of WORK, need food easy to fix and eat, not a lot of preparation or cook.....freeze dried - just boil water), Vs. 90+ days, things are stabilized, cooking/cleaning/food production is figured out, water source is figured out. At this point, longer food preparation is OK, like soaking beans etc., and more "clean up" is OK, like pots and pans etc.
Mechanical advantages are awesome, and highly recommended, however, they are "limited". Take for instance, the "camp stove", definitely easier to use than a wood fire and makes a LOT of sense. However, eventually you WILL run out of fuel, what is plan B? Taking a camp stove outside to cook , when it's 65 degrees and sunny, is a piece of cake; what happens when it's -10F outside? Or raining? Or it's 110F outside. It's one thing to suck up the suck on a couple of day camping trip, when you KNOW it's going to end and it's temporary. It's completely another thing to have to do it, day in and day out, no end in sight
Just some things to think about, see signature below.
