I load my 4-drawer craftsman box to the brim when i travel anywhere with the truck. I carry full sets of 1/4, 3/8 and 1/2 driver sockets, all my ratchets, extensions, screwdrivers, wrenches, pliers, hammers, specialty tools, electric impact gun, and a huge assortment of electrical connectors, wire and fuses.
The truck always has a towstrap, shovel, shackles, jumpercables as well as spare hub, TREs and some misc fluids. I also have a high-lift and bottle jack.
Better to be over prepared than under.
this is close
full sets of 1/4, 3/8, and 1/2 sockets with matching ratchets, a breaker bar, and a pipe (for added torque)
common sized sets of metric ratchet wrenches, with the rest of a full set made up of non ratcheters
needle nose, channel lock, and vise grip pliers
5l anti freeze and motor oil. A bottle of PS, Brake and tranny fluid as well as a thing of methyl hydrate
recovery strap, chain, various size ratchet straps to include vehicle tie down straps (something like 5,000lbs), snatch block, winch controls, and when applicable 10,000lb winch.
I need to get a taller jack, but im gambling right now as the funds are not there for the one I want.
I also have duct tape, electrical tape, wire cutters, and various screw drivers.
Right now there is a 20lb sledge and stuff for measuring out distances in a field
