whats everything you could possibly need for a on trail tool kit for a cherokee?

 

My wife says I carry a spare jeep in mine and I still don't always have what's needed.
I carry spare shafts front and rear, several u-joints, belt, oil, tranny fluid, gear dope, water, misc. nuts and bolts, spare drive shafts, RTV, brake cleaner, ether, CO2 tank, a big ole tool box full of wrenches, sockets and screw drivers, bailing wire, zip ties, several kinds of tape, couple of spark plugs, garbage bags and a tarp. I'm sure I'm forgetting something but it's a start.
