I've had my 10' 4x4 Sport 3.92 LSD for a couple of weeks now. Took it into the back hills over the weekend and found a Massive mud pit about 50ft across that was a good foot deep of sticky, tacky mud and never had a problem playing in it. The truck did great pulling me through it in 4Hi over and over again. I did have a factory locker in my 02 Silverado though and I had it in some wickedly bad places and it never failed to pull me out. Wish Dodge would offer it. The LSD should be standard and the locker should be the option IMO.
