If your "packing" plans just involve packing the groceries or latest fashion trends from your nearby TJ Maxx retailer, then get a 2wd and be happy with the simplicity and slight bump in fuel efficiency. lol
Sounds like you are in the service, possibly as Osan AB?
I was in for multiple tours in forward infantry, but apparently not enough to qualify for the Chrysler Military discount.....I feel your pain in wanting to get back home ---
Sure it is not impossible, but why not get a stripped down X 4wd (even a used one) It would be so much nicer than trying to retrofit a 2wd unless your budget is wide open and if that was the case, you would probably be purchasing a 4wd for starters.
Keep the faith.
