We have a Coleman, but we also have sterno stoves (the 2 burner models) and are stockpiling both sterno cans (both sizes) and fuel for the Coleman.
We have been stockpiling bottled water, medicines, canned soups, canned vegetables, canned fruits, and canned beans and meats (protein) for some time now. We have a 6' 2 door cabinet in the basement for just the canned foods-it's almost full.
I remember back in the Reagan administration (not sure 1st or 2nd) reading a letter in the Ann Landers column. A reader told her about discovering a can of tuna that had an expiration date in the Nixon administration! She stated that she'd discarded the can, but wanted to know if it would have been safe to eat. Ann consulted with some chemists, canning operators, FDA staff, etc, and their conclusion was, the food might have deteriorated a little in taste, texture, and vitamin "availability", but it would have been safe. More recently, I saw an article on a grocery store that had gone out of business way back in 1969. Somehow a can of corn from it had gone into storage-don't ask me how or why, it's been a few months. Anyhow, the can was taken to a lab, opened-and the corn inside looked as if it had been canned last month. It was perfectly safe to eat. So I say, regard expiration dates as interesting suggestions, not commandments from God. At least for cans that require a can opener...Not sure if I trust the pop top canned foods as much, and it's getting harder to find the old fashioned, less convenient cans.
I suggest all preppers who NEED their morning coffee make damn' sure they have a camp or stovetop perculator coffee pot, and filters. We made coffee with the stovetop on a sterno stove-it was very hot and very good. I used non dairy creamer with it...With the electric, the creamer just slowly dissolves into the coffee. With the perculator, the creamer disintigrated on coffee impact. It was really impressive to see.
I recomend a ‘Rocket Stove’
