This would probably be better in the talk forum, but here goes my answer. I have a 2wd and I am gonna go the electrac route for a selectable locker/lsd. With that and nice tires I can do most of the stuff I want to do, mainly fire roads and oteh stuff, but not necessarily rock crawling or mudding. I figure that since it is an isuzu it will live doing that until I get another car in the future for a daily driver, I figure 5-7 more years, at which point it becomes a project car. Whatever these guys tell you, an isuzu with a nice locker can do many things you couldn't dream of in an explorer or like 4wd. Course, I would get a winch too cause stuff happens.
