I'm working on compiling equipment for survival systems for both of my vehicles. I want them to be a three-part system; one part that can be grabbed from the vehicle and carried as a backpack on foot with all the necessary survival and emergency accoutrements if necessary (obviously the smart thing in most cases is to stay with your vehicle but you never know what you might have to do), one part that is vehicle specific and thus would be useless weight if carried along on foot, and the last part winter-specific and can be stored separately at home during the summertime. Has anyone used a similar system or found another that really works for them? I'm open to any and all suggestions. Part of my inspiration for wanting to do this is I am having a permanent change of duty station within the next couple of months and it very well could be to a fairly cold, rough, and remote environment. What do you guys keep in your vehicle that you have found to be practical and use on a regular basis? I'm thinking practical stuff that I can actually use in realistic, likely situations... a car accident/hitting a deer/etc, getting stuck on a muddy or snowy road, car trouble, getting stranded (shouldn't happen if you're prepared but stuff happens especially in winter) I'm really curious to see what people carry and find to be useful. What other situations have you thought of that could happen while you were out and about in your vehicle and prepare yourself for? I already keep a military trenching shovel in the car after getting almost hopelessly stuck in the snow a few years ago and certainly would have been if I didn't have that shovel. I'm also planning on getting a set of recovery boards and some snow chains for wintertime if my next station is up north. For the backpackable part, I really want waterproof rucksacks and was wondering if anyone had a durable, relatively inexpensive dry bag they were happy with that could be worn on your back? I've been looking at dive bags such as the Cressi dry Gara backpack if you're curious as to the style I'm looking for. I know Patagonia makes a similar bag and they would repair it if it got holes etc. down the road too. The Cressi seems like it would endure years of being kicked about in the back of a vehicle though and is pretty inexpensive. Thanks for any suggestions!
