I'm pretty sure that we are getting our collective chain jerked there...
On the serious side. Here's what goes out with me each and every time I'm not going to the mall, in no particular order.
1) Recovery points front and rear.
2) Ax and shovel (not needed everywhere, but really nice to have around here)
3) Recovery gear. Snatch strap, chain, appropriate sized shackles.
4) 550 cord (50' - 100' or so in a fun color)
5) Water (everyone has at least a liter bottle of their own along)
6) Leatherman Wave multitool with the set of attachments.
7) 48" Jackall, base and attachments (lifting, pulling, clamping) This is a pretty controversial tool to bring along, but I like, and use mine a lot for various things)
8) Air pump, sized for your tires. Mine's a Viair 880P.
9) Quality mechanical dial air gauge that reads down to 5# pressure
10) TP in a plastic bag
11) Couple of large garbage bags
12) Couple of zip lock freezer bags in quart and gallon sizes
13) Tools in a tool bag
14) Overnight bag.
15) GPS with high resolution mapping chip installed
16) Sidearm and spare ammunition
17) Coat and liner
18) Moccasins (I wear jump boots all the time so something light is nice to have along)
19) Wool shirt and spare wool socks
20) Lunch and munchies
21) Flashlight
22) Spare batteries
That sounds like a lot of stuff, but it's not really all that heavy and doesn't take up all that much room.
