Yes your location is tough to find older vehicles that aren't cancer ridden and it would depend on the truck as to whether it was wore out or not at 150kmi.
Like many folks on here, I sense that you're up for a project, not a pull n go setup. That's fine, more power to you, it depends if you want a project or you want to hit the road.
I'll add this. You are considering this to travel yet appear to be relying on the tools, shop, discounts and knowledge at home when finding the "right" setup.
I'm thinking about when you're 1500mi away from pop's barn. Then all you have is the knowledge and whatever tools you packed with you.
Hence my reccomendations for keeping it simple in that respect. Good luck with whatever you choose.
