Much the same here. Tool bag with hammer, hacksaw, big wrenches, flashlights, bailing wire, bunches of zip ties, etc.. and two tool rolls with sockets, gear wrenches, screwdrivers, pliers, etc... I put all three of these items into a case like a Pelican case that can attached to the roof rack or stowed in the back, depending on my load out.
I use the cargo barrier between the backseat and load bay, and have misc bungies strapped to it, a fire extinguisher, flashlights, first aide kit, wet wipes, ARB field light, my HAM and CB antennas (when not in use), and 4 collapsible walking sticks for the family members.
In the cargo wells above the tires, I keep tree shears, spare FRS radios, spare recovery shackles, gloves, headlamps, zip ties, toilet paper, batteries, trash bags, air hose (for airing up) misc tire gauges/tools, etc...
In the cavities aft of the wheel wells (where some have A/C system) I keep a super siphon, jumper cables, emergency hand crank radio, 8 ton bottle jack, binoculars, and 3x30 recovery strap.
