Agree with the list and additions as well, but would add a backpack so that you can carry all the stuff you'll want if you need to hike out.

I always have my USMC "deuce" gear, see photo, in the back of my H2 loaded with cartridge belt/H-harness; two full canteens; first aid kit; gloves; gun, holster, & ammo; knife; cord; emergency blanket; flashlights (2 small aaa headlamps); flask (w/ single malt Scotch); GPS; Gore-Tex jacket (w/ liner); hat/headband thingy; Gore-Tex rain pants; a few extra fleece layers; map; toilette paper; lighter and matches; lighter fluid and/or Coleman fuel (so you can start a fire with even the wettest wood); extra batteries; cigars; water purification tablets; emergency food; whistle (gun usually works better); Excedrin (cures almost any altitude ills). -- It all weighs about 25 lbs and can keep me alive for days.
