I carry a sleeping bag - one of its thermocell, now a British Royal Air Force rescue plane sent. May seem extreme, but around me travel in Europe and Scandinavia, and even in some parts of England - if cold - it can be cold!

I took the road less traveled. Now I'm LOST.

A lot of good ideas here. A lot of gear to carry.
Every situation is different and there will always be something you wish you had, but left out often because there was not enough room and the likeliness of needing it in an emergency is slim. Murphy's law will ensure you really really needed that one or two items you left behind.

I recommend having a readiness tote pre assembled with the expectation that in an emergency where you are with your vehicle, you can get by for several days without help. How many days worth of supplies will always depend on how much room you can allocate and what kind of trails you use. Figure that if you travel very seldomly used or lesser known trails you will want to carry more gear. I would not pack for less than 3 days worth of supplies.
3 gallons water - more is always better if you have space
firestarters
large wool blanket and/or capable sleeping bag
multitool (leatherman, gerber, etc)
general tool set to handle emergency vehicle repairs and spare oil
1 extra set of clothing in a sealed bag including cold weather gear and waterproof gear (cheap plastic fishing clothing or a plastic parka)
portable water filter
3+ MRE meals (you can buy these anywhere, I get mine at www.sportsmansguide.com)
map/compass (and know how to use them, due to Muprphy's law none of your electronic GPS equipment wll work or you will run out of battery power)
spare batteries as needed
flashlight/spare lamp
quality hatchet
A few trash bags - these have hundreds of uses
compressable backpack should you need to leave the vehicle
metal cup for eating/cooking/drinking
550 paracord - 100 - 500'
boots


Just off the top of my head.
I have a smallish rubbermaid container in the back of my truck with this kind of stuff. You could fill these forever with "might need" equipment, luckily a lot of this stuff is compressable or small. More people = more equipment. one gallon of water per person, per day is recommended.
