Since the ECU left us stranded once, I now carry a spare.  I also
have an O2 sensor, ignition wires (old ones from the last change),
distributor cap and rotor, oil (at least 1 full change worth), oil
filter, air filter, temp II sensor (from the last change; still
works), and (of course) coolant.

I didn't go out and buy all this stuff at once, but just accumulated
it as I was changing stuff doing preventive maintenance, etc.  The O2
sensor is new from the Bus Depot (generic U-splice).  Most of the
stuff fits under the weekender seat or in a rubbermaid tub that I
always carry anyway.

This is sounding almost like that "what do you carry in your bus"
discussion that's summarized for some people on www.vanagon.com.  I
always liked the guy who said "A Colt .45 and I don't care who knows
it either."  :-)  [Please, no gun control flames or discussion...
