Intersting thread....I love the AWD on my wifes CRV, the AWD runs 90% FWD until needed, then transfers more to the rear. It is worry free, no buttons, levers or switches to worry about. It does a great job of keeping her safe.
The 4WD units with low range these days tend be more for the people and vehicles that can go off road. My Tundra is 4WD and I wouldn't have a pickup without 4wd, it has saved me several times. Several times when towing the TM and once when I pulled into a sand road and stopped. 2wd will dig you a very nice hole for your rear tires when attempting to start off again.
In these parts, you never know when a spring snow storm can cause bad driving conditions on a return trip home! I would never drive a pick up on snow covered roads in 2WD with 4000 lbs pushing you down the road!
Good Luck!
