In addition to good ol' knobby tires - I would look into getting some on-demand lockers installed. That will guarantee you are getting power to all wheels. You might want to look into ARB or Ox Locker. If you are on a budget - you might also want to look at Lock-Rite as well. They are an automatic locker - which have their own set of pro's n' cons.
