basic kits will vary depending on what you think you'll need.
my basic 'kit' includes my socket set which i strap to my spare, a small array of screw drivers, and other specialty tools for fixing stuff on the trail. (36mm socket, 12 point sockets etc)
air compressor for airing up.
couple bottle jacks and wood for em. i gave up on high lift
spare parts; for me these include 3x ujoints, a wheel bearing, spare D30 axles, driveshafts F/R, (i don't carry them with me though; keep em at home) balljoints, spider gears for the rear 8.8, brake lines, various fluids, jumper cables, fire extinguisher, first aid kit and a big ole' moving blanket that i lay on iif i need to wrench under the jeep. chain saw if i feel like it
or the axe.
and yes duct tape
shot guns, rifles, and ammo can be added if the zombpocalypse starts on dec 21st.
