Mrs Lost in the Woods is the same as your hubby.
She thinks I should be committed.
I do the same, I go through and rotate stock.
Canned goods last much longer than dates as long as the cans are not bulging. I am fortunate because I made friends with a store owner and the gov cut his LINK/EBT for people that need it. He sells me huge quantities for inexpensive just to clear his shelves.
You are correct as for time frames. Flour products need to be used and replaced on a schedule. Canned fruit and vegies last as well as soups. I use 5 gal buckets with lids to keep it sealed.
I have about a 8 month supply and still building. I do this so if people in my neighborhood need food, I will help at all times. Some crops will be late, but there will still be vegetables ( only more expensive ).
I keep some cash in a sock so the bank cannot get it.
Kerosene lanterns and a small solar panel.

So I am not Alone!!! kekeke Here is what I put in my survival... The power adapter hooks to car battery, the solar panel charges battery. This way you can plug in some items as you need. I thought I was genius Todd not so much! keke I also got solar panel and kit for RV but it wont power much more than these two items.
