...To someone else I'd say know how much you're going to use the truck and your cost going each way, then model the costs. If economics is your most important consideration your answer will come from the model.
..Your choice between one of those or possibly electric power needs to suit your own preferences and priorities.
I think if you modeled cost of different options you'd find messing with trucks this old is not the best option, gas diesel, or whatever.
If that's the case, and even if it's not, just do what makes you happy, if you like a big or small gas engine use one, if you want a diesel run one you like, if you want something else just go for it.
If this old truck hobby and engine choice comes down to a business decision then is it really a hobby, are you still having fun and doing what you want to do just because
you want to?
