I've had four really close to being stranded experiences on the trail where i was over 10 miles from the nearest house and 50 from the nearest town. The things that i've found i really needed werent those listed.
I had a fuel pump power wire burn up on me so in that case, a voltmeter with a continuity alarm and an extra 10 feet of electrical wire, electrical tape, and a knife came in handy.
I had a dirty fuel tank that got too low and flushed some major debris into my carb and it would only run while choked. in that case a new fuel filter was crucial.
I had a power steering line that bumped loose, got into the fan, sliced laterally, and was impossible to plug with a hose clamp. I found out when i lost all power steering and heard the pump start cavitating. In that case, duct tape, 4 tire plugs, zip ties, and a quart of tranny fluid got me home.
I had another experience where my battery hold down bar came loose and shorted across the pos and neg terminals. I started losing lights and indications and my wife yelled fire. It was very humbling when everything went dark and we were halfway up a pretty good trail. I opened the hood to find a fire ball and i quickly used my shirt to knock the bar off the terminals but not before the terminal melted. In that case, duct tape, extra nuts and bolts, and alot of electrical tape got me through it.
