I hate to ask the obvious, but how about turn around and drive back the way you came? I assume the vehicle died or ran out of gas in which case I would bring 5 gallons of gas. I carry a lot in the truck in the event I have a breakdown, but I generally don't plan on staying more than one night. If snowed in I would walk back on the same road I came in on as at least I know the general time it took to get me from where I knew my location to now I am lost.
Items in the truck I keep
thermal blanket
extra shirt, socks and shorts
mora
axe
corona saw
matches
lighter
fire stell
metal water bottle
flares
backpack
4 bottle of water
4 packages of crackers with cheese or PB
road flares
wire
50 ft of cord
multi tool
hats
meds- aspirin & benadryl
