I doubt that will help with some of the places I've seen Sam get his Disco into :).
I have a very basic tool kit that lives in the car & I have a bag that I throw all my spanners, 3/8 socket set, hammer, big shifter & multis, big screwdrivers/levers, cable ties, tape, etc when I go out with you guys.
Believe me, you can never have enough tools when you go out in the bush - I think I've used just about all I carry at some stage or another.
