Just wondering if we have any member here that are part of the preper crews? The thing I was interested in is the shelf life of different foods. Many claim life of 10 to 25 years but in doing some research I'm finding that to get that length you have to have constant temps of 50 degrees or less and that isn't practical in the lower 48. Has anyone found what they consider to be the best and longest lasting products. Any thoughts or insights would be appreciated.
