you guys are talking like a rover can't go anywhere off-road when the CDL is un-locked. Remember a DII has traction control that automatically applies brake to the wheel that is slipping so power is sent to the wheel that has traction.
BTW, does anybody know if traction control works in 4hi? mine only seems to work in 4lo.

Without CDL, your 4x4 is potentially 1 wheel drive (assuming you have open diffs.)... NOW, throw traction control into the mix and lockers become less of a necessity for the average weekend wheeler. You can have CDL and 2 wheels in the air and still make good forward progress. Out of the box, Discos with CDLs are far more capable than many highly modified rigs.

edit: ah, I just saw the posts above (2nd page!)....so, the ETC applies a brake to the spinning tire. This in essence sends torque to the tire thats not spinning. Interesting. Does that smoke the brake pads? Is this common in other SUVs/trucks? Sounds like this feature is an intermediate between an open diff and an LSD?

Just today i was driving in to work and went over pot hole as i was braking and traction control came on. I have experienced it a lot when in 4hi and going in a hole or coming off a curb to fast where the wheel gets to spin faster than the opposite wheel on the same axle.
if you dont have the rave manual handy the brakes section for the DII is loaded on my website which explains how it works together =)

An unlocked center diff sends the torque to the path of least resistance. That means if your rear wheels have no traction and your center diff is unlocked all the power goes to the rear wheels and in an off road situation you sling mud everywhere and don't go very far. Lock the center diff (and the front and rears if you have lockers) and the torque will still go to the front axle and pull you through any obstacle that would have gotten you stuck without the CDL.
So, other SUVs with part time 4wd (no CDL) do not have the option to lock the center diff, so they are always susceptible to the above situation.
I don't think there's one specific thing that makes the Disco bad *** though. The CDL and full time 4x4 are huge factors, the 12-14" (or some ludicrous amount) of stock wheel travel helps. They're really just built to be brutal off road machines.
