It seems like a lot of people here don't understand that circumstances might be different in different places. This post itself assumes the only reason is to transport people, but the truck can do more than that.
If I lived in a rural place and needed something that could tow, transport, and go over tougher terrain, I could see the usefulness of having a truck around. Not everything is in a comfy city where everything is within a couple miles.
Now where I currently live, I'd never dream of getting a truck like that. So much hassle and the roads are too small. But I could see it being useful for someone else.
