AWD totally rocks in the Utah winters as well as the off road camping/hunting. Can you accomplish the same things with a slow cautious thinking person in a well equipped and properly weighted FWD? No, but close. The thing is with AWD it just does what you say, and not what you don't with a larger factor of safety or level of comfort. Here in Utah, there is frequently black ice on overpasses etc, and the AWD just handles it and you never know, whereas those without are the guys you see on the side of the road in the ditch upside down.
If you live in Arizona and never go offroad, you probably don't need it. As for me the cost and 2 mpg I give up is totally worth it the first time it snows!
