You are getting good advice here.
I think the only circuits you need to worry about are bulbs, voltage regulator and fuel gauge. If you replace the 6v generator with a 12v alternator, AND change all bulbs to 12v, you are most of the way there.
A solution is to use two 6 volt batteries in the truck, wired in series. This gives you a 12 volt truck, but if you have a fuel gauge concern, merely hook it up to one 6 volt battery only.
