I recently was asked to jumpstart a guy near my home that was parked on the side of the road. I had to nose up to him, so I pulled a U-turn and I ended up with 3 wheels off the pavement in an incredibly soft ditch (front wheel sunk all the way past the hub). If I'd been 2wd, I would have been stuck. As it was I simply put it in reverse, and backed out. Didn't even hit any switches since it's got auto 4x4.
I've never needed 4x4 while towing, because I choose not to take my camper off at least fairly decent gravel road. But I do like the low range for boat ramps, or pulling one axle up on a ramp to change a tire, etc.
