Ok. So I'm coming from the Disco 2. And have an 06 l322. I don't see a Cdl. What do I need to do to make this thing ready for overland adventure mechanically? Running RSW 4dcan for lift and 255 55r20 all terrains. Does the 2006 have a computer controlled center dif lock or something? Anyone out their fit a rear locker? I feel like such a newbie.
