Incorrect for modern vehicles equipped with limited-slip differentials...

Limited-slip differentials are primarily used on 2WD sports cars. 4WD is a MUCH better option: if you lose traction on one wheel you have 3 others providing traction vs one. I haven't seen any SUVs where this is an option, anyway.

Isn't that what AWD does? It's available in SUVs, sedans, and even a minivan.

Limited-slip differentials are offered for 2WD vehicles only. I once had this on a Ford F-250 pickup, which I was not very satisfied with (it didn't seem to work as advertised). Here is a good explanation comparing AWD to 4WD:

If that isn't enough, here is another:

The bottom line is if you want maximum traction while off-road get 4WD. AWD is perfect for people that only drive on roads that may get occasional snow and ice.

My Dodge Durango very definitely has 4WD and a rear LSD, though it was not in the options listed in the back of the glove box. I rebuilt it four years ago. It was very difficult to identify from outside of the pumpkin as same diff could be fitted or refitted with/without it. The vehicle is definitely a goat with a small turning radius, plenty of ice and snow clearance, and tows large glider trailers very well at impressive speeds. It sucks gas though, especially the ethanol infused stuff.
