800 mile roadtrip

Just set yourself up with the basics and don't overthink it. Newer cars break down, too; and people don't think twice about driving them on long trips. The only difference is that with an older car you have a fighting chance of fixing it yourself on the side of the road. Not so much with newer cars, their issues tend to be with electronics and you're not fixing that on the road.
Remember- back in 1908 they raced from New York to Paris, and they didn't even have gas stations along the route, let alone NAPAs or Autozones.
