I'm of the mindset "it's better to have it and not need it, than need it and not have it".

I'm also waaaaaay over prepared for vehicle repair with my 2nd gen and pack enough stuff to rebuild half of the front end or anything that gaurantees me walking if it breaks including one each of:
Front CV axle
Inner tie rod
Outer tie rod
Upper ball joint
Lower ball joint
Steering idler arm
Pitman arm
Front brake flex hose
Rear brake flex hose
Clutch flex hose
Steering shaft upper coupler
Steering shaft lower coupler/rag joint

And then there's more: couple feet of 1/4", 3/16", 3/8", fuel hose, metric brake hard line, heater hose "U" to bypass if heater hose blows, 1 radiator hose (same hose for top and bottom), hose clamps, spare belts, a quart of brake fluid, ATF (power steering), gear oil, gallon coolant, zip ties, bailing wire duck tape, JB weld, Toyota FIPG sealant, electrical wire, connectors, fuses.

And all the tools to do all those jobs. Sounds extreme but it's only a bag of tools about the size of 1-1/2 shoe boxes and a tool box about 30"L X 12"H X 10"D for all those spare parts. I'm admittedly still fairly new at off-roading but it's all about piece of mind. Some guys have no issue going with only a balogna sandwhich, a bottle of water and flip flops. My mind needs to be prepared so I can enjoy the trail without worry.
