I use my truck as an actual truck and put thousands of miles on it each year. It still has a 6v system with a generator and works just fine.
The sealed beam halogen headlights are as bright and shine as far as any modern vehicle.
Ditto for the taillights.
Unless you're adding a bunch of electric accessories, I see no reason to do the switch just for the sake of doing it. Also, you can jump start your 6v truck from a 12v vehicle in an emergency without harming the starter.
