I ALWAYS, ALWAYS travel with my fluke 77, a couple of jumper wires with and
without 12 volt lights in them, a 100 psi tire gage, an infrared
temperature gage, 3/8" drive socket and ratchet set from 3/8" to 3/4" sized
sockets. Stubby and other length Phillips and standard screwdrivers,
extensions, pry bars, etc. God only knows what else is in that carry on
box. If you have it, you probably won't need it, but Murphy will get you if
you leave it at home.
