Just off the top of my head...
Tool Kit:
End wrenches in standard and metric
Hex/torx multitools
3/8 sockets in standard and metric
An assortment of larger 1/2 drive sockets
Front hub socket (35mm is what it uses, but I carry 36mm 6 point because it works on the Yota AND Jeeps)
Diff drain plug (24mm 6 point, 15/16 works in a pinch)
A
Gorilla wrench (and included lug sockets) to use as a breaker bar
A cheap cordless impact/charger
A multimeter
Zip ties
Gorilla tape
Electrical tape
2lb sledge hammer
Screwdrivers
Locking pliers
Side cutters
Pry bar
Chisel
Varies electrical connectors
Spare wire
Tire kit
Some brake line fittings (mostly a way to plug a hard line if it splits, or cap the hardline if a hose tears.)
A bag of various spare hardware
Depending on the trip I will add spare fluid for everything in a separate bag and before I installed RCVs I would often carry a spare CV shaft.
Inside the truck I ALWAYS have:
Fire extinguisher
First Aid kit
Jump box
Flash light
