Here's my approach. My travel frequently takes me from a major metropolitan area to remote wilderness settings. I drive an old 4x4 truck that looks like a decommissioned phone company vehicle. On the outside, there's nothing that would ever give you pause to look twice.
But inside...
-Enough camo netting to cover the entire rig
-Signaling gear: orange duck tape for arrows, SOS, etc. (it's a white truck)
-Full size spares (2)
-An assortment of tire patching tools and materials
-Old parts that may still save my ass in a pinch: u-joints, lug nut, belts, hoses, spark plugs and wires, cap and rotor. etc.
-Other auto stuff that might come in handy: fluids (ATF, HEET, oil, coolant, brake, etc.) filters (oil, air, and fuel), etc.
-Onboard compressor / jumpstarting unit (Solar battery charger and bicycle pump for when the main unit craps out...I can do a lot of things, but I can't create electricity or compress air on my own.)
-Self Extrication Tools: V-Bar tire chains, HiLift Jack, winch (2), 30' logging chains, assorted recovery/tow straps, clevis (3)
-Tools: axe, 24" & 72" pry bars, 16# sledge, shovels, pick axe, big bow saw, machete, and basic auto repair
-Folding Bicycle: 24" x 18" x 12", currently being converted to hard use scenarios, (solid tires, gun mount, etc.)
-Inflatable Stearns Canoe, collapsible paddles, PFD, whitewater helmet, rescue rope
-Vertical gear: harness, rope, anchors, grappling hook
-5 gallon jerry fuel cans (4)
-Assorted siphons for assorted fluids (none of which require me to use my mouth for suction, chemical pneumonia = bad!

)
-Dual fuel (white gas/unleaded gas) Colman two burner stove & two mantle lantern
-Military officers mess kit for 8 (yeah, like I'm gonna wash dishes, c'mon)
-20,000 kcal of food (roughly 10 days)
-7 Gallon water jugs (3)
-110v Inverter
-EMT First Aid Kit (FAK)
-Collapsible litter
-The mighty toilet paper
-An arsenal that rivals the National Guard
-Enough clothing to keep two other adults warm and dry
(I live in the Rockies and seem to have made friends with many people who have no concept of climate as it relates to altitude. Oh well, I guess I can always eat them. :barf: )
-An assortment of well-worn footwear decommissioned with 3 months of life remaining
-Sox, sox, and sox!
-And a BOB that is constantly tested and improved upon
I realize much of this may not be practical for everyone, (especially with all this extra weight and fuel at $3.00/gal & climbing), but maybe it will get you thinking about something that works on your end. Is this overkill? Absolutely. Has it save my ass? You betcha. It has also allowed me to capitalize on some awesome spontaneous adventures and provide several much-appreciated rescues/assists.
On the upside, I don't have to pack as much as I used to for elk/deer/pronghorn hunting. I've also done the same exercise/stockpiling for my dual sport motorcycles and mountain bikes. :thumbup:
One Final Note: I'm not eager to volunteer to become a refuge. If I can stay at home or make it home, I will.
