Lock the center and rear and run some really thick oil in the front.

If you lock the front, you lose turning radius. If you lock the center, you transfer all the force(s) of acceleration & braking directly to the drive line. A locked rear is fine. You lose a little turning speed, but no biggie. Run a heavy oil in the front diff, and a super heavy in the center. Keeping them unlocked will allow for all the advantages of a differential, but the heavier oil will keep things "locked" similar to a limited slip diff unit. If any of the wheels get bound up, jammed in the rocks, etc, you'll still have the differential movement to keep from destroying your entire drivetrain.
