This is an interesting thread. I have not done any off roading yet, as my 4runner is not ready. I had no idea of all the equipment needed to carry. That's like 400 lbs of recovery and repair gear.
A prius is looking better all the time.
I agree with [MENTION=118321]Jetboy[/MENTION] about it all depends on what you do. [MENTION=118321]Jetboy[/MENTION] drives the Rubicon Trail and has a rock crawler, that's a different ball game.
You have a 4Runner so its ready. My very first exploits where 400 dirt miles on a Subaru Tribeca with zero tools, zero anything, and no proper spare. That includes muddy Southern Utah 40-mile long roads. Not a great example to follow but we never got close to having an issue. Then I added AT tires and a foldable shovel. Never got stuck in that Subaru or my next Outback which saw a lot of offroading. Solo with kids to boot (I did get stuck once in another of our Subarus--one that "never" goes offroad, lol).
Overtime, I accumulated the basic recovery gear everyone carries, mostly out of courtesy. However, there is a separate thread for recovery gear. There is no need to go overboard, but it is also wrong to be like me at the start and have nothing at all.
As for tools, you don't really need any tools until you start pushing the envelope on either the size of rocks or the speed.
I do nowadays carry tools that would allow me to do something about the suspension, a variety of "band-aid" tools like different sizes and types of zip ties and so on and so forth, 12v impact wrench, breaker bar, ratcheting this and that, etc. But the reason is that now we do some difficult trails solo and we also do more remote desert driving than before. And it all fits in two kinda small boxes on the roof basket or in one midsize box in the back when the roof basket is not mounted (which is usually the case).
If you stick to trails rated moderate in the Charlie Wells book--his updated Arizona book is coming early next year; he was here 2 months ago re-driving all his 100 trails--and avoid obviously dreadful weather conditions, you need only very few and basic items.
BUT, I always carry 5 gallons of water when on a desert trail,
no exceptions. I do carry less on Sedona and Flagstaff trails which are shorter and milder in terms of weather.
So, yeah, I'd say if there are three things I consider actually required that would be water, first aid kit, and the other one is good tires. If on a trail that you cannot walk out of, you want to have someone know what to do if you don't check in by X hour or have satellite communication.
Of course, the above assumes that every important component on the vehicle is in really good condition, starting with the battery (I do always carry a jump starter nowadays).
EDIT: I guess the bottom line is that carrying nothing like I once did is wrong but that if you read too many forum posts, you will need a semi to carry the stuff you "need"
