What ever makes YOU happy. It's YOUR truck. What is going to give you that 'thrill' every time you get in it? Some like vanilla, some like strawberry.
However, I kept mine mostly stock. You see very few bone stock trucks at car shows. EVERY ROD has a V-8 it seems. Seems like that has become 'vanilla'.
If you upgrade a few 'safety' features and a 'creature comfort' or two, you can have the best of both worlds, stock look with modified upgrades.
