As far as tools, a couple of screw drivers, a pair of pliers with wire cutting capabilities, a set of 1/4" drive to 9/16" a crescent wrench and tire changing wrench. Parts - some fuses, a 10' piece of wire and a roll of 3M 33+ electrical tape and maybe a head and tail light bulb. Beyond that, cash and/or a credit card will fix most other repairs as much more then a carb adjust or tighten a small loose nut or bolt will need a garage.

This time of year, Sears have a small sets of tools in a plastic box which may cover any usual on-road repairs
