Seriously though, I've got a fairly complete tool set in both trucks, more complete in the trail rig of course. Tow rig has an extinguisher, 4-way and bottle jack, tires chains, cargo straps, some fuses, etc.
Trail rig has things like tow straps, shovel, saw, ropes, chains, stuff to improvise climbing harnesses, spare fuses, tape, bailing wire, flares, two rear axles, set of front axles, two spare unit bearings, spare ball joints, 5 qts oil, ATF, coolant, filters, serp belt, power steering box, u -joints for axles and drive shafts, squad size military first aid kit, extinguishers, 1-11/16 and 1-5/8 sockets with adapters, breaker bar, replacment bulbs for head/tail lights, misc nuts/bolts from 1/4" to 1".
Also have spare wheel studs and lug nuts,
When leaving my driveway (actually going really far out into the boonies) I add the 3/8" drill and bit set, sawzall, 4-1/2" grinder, drop light and extension cord that can be powered with my 750/1500W inverter (dual batteries and 170 amp alt help).
I need to find some welding rod to take as well to use with the jumper cables and dual batteries.
Then I toss in my backpack with cooking stuff (fuel, stove, pans, cutlery), water purifier (not just a filter), tent, sleeping pad, candles, compass, gps, TP, binocs, emergency blankets, matches, firestarters, folding cups, carabiners, ropes, water containers all incase I need to hike out from somewhere.
Backpack and first aid fit in the cab withthe extinguisher, rest in the Knaack box on the flatbed
