I agree Chevy has the most compatibilty between the years 67-78 or so? That makes parts very available, that is if you can out gun the junkyard dog.

Apocalyptic in my minds eye is mass hysteria, people killing other people, not so much from disease, but for food, water, etc. (That is after there are no more stores to loot) So armor will be a definate must, but you will have to fuel it... Hybrid DUKW?

I'll leave that kind of thinking to the story writer as I don't ever want to think that is possible, at least not in my lifetime. Aren't the Dutch predicting it in 2012?
