I don't have much to add except the one element that I feel is missing from all these bug out and survival plans, is bringing along a fit body. I see a lot of overweight and slow moving people at organized shoots, gun schools, and gun shows, and I know these people are prepared with the equipment. But truth be told, the rate limiting factor in their survival is lack of personal fitness. If gas runs out you will need to walk or self propel, and you do need to be able to move quickly sometimes. Part of my routine is cardiovascular and weight training so that I am not limited whatsoever by my ability. I would also include a mountain bicycle and a some good shoes as part of my bug out plans. I might need them.
