I find with the LSD (not the dope), it makes a big difference in 2WD over other 2WD trucks/SUV I've driven even though the LSD is not the best. Someone said the driver makes a big difference and I would agree. I tend to drive like if I'm in 4x4 all the time, so it doesn't take much for me for the 2wd to be insufficient and have to shift in 4x4. I would probably be more careful if I did not have that option.
