Sure thing, Internet is full of offerings of all kinds (as a seed, the first hit is below). For me, in my old 4x4, the most often used things were - a knife and a machete within driver arm's reach (on MOLLE wraps for the roll cage), comprehensive medkit (accessible from rear seats and cargo compartment), and two bags hanging from a MOLLE patterned tailgate table with towels, soap, gloves, rain hats, windbreakers, space blankets, and all that small but useful stuff. Those two have been somewhat of a PITA, though, because they interfered with cargo, so I'm not sure I'd want them there this time - and it looks like all that stuff will just go into the lunchbox.

But what worked for *you*?
