What do you carry with you?

[Synchro909]

When we are on a long trip, we are usually outside phone range so I have to expect that if the car stops, I am the one who will have to get it going. I carry a set of tools (spanners, screw drivers, pliers etc,, jack and handle. There is a distributor and carburettor (never have needed either), some electrical wire, fan belt and test light. A spare tube (from when we couldn't get a decent one) is always there and a stick of Kneedit (an epoxy putty).
Because a repair might take a while, we have a toilet roll, food and water. We have had to make some what I think are clever improvisations but we've always gotten home. IMO, the best thing to take is the gap between your ears filled with knowledge about your car.
