Seems like similar stuff to what I have thought of, except for the crimper and wire connectors, and the circuit checker, good small items to include Don. In my 4x4 we have 4x4 blocks of wood and a hydrolic jack, and in the sport ute we have the earthquake kit(emergency food, water, stove,.... they have these great food bars the coast guard uses that are a three day survival amount for one person in each foil pack, that can take extreme heat and cold, and still be good for 5 years, so we have a few of those in there too(they are only like 3 bucks a pop) 4 bars =6days of food for two of us. The gun idea would get us in deep dodo, but not a bad thing either if it's legal in your state.
