Until you experience it, its hard to understand. Its not so much the speed, or acceleration, but rather the extra driven wheels. I used to fight using 4x4 in the rain, but, even when starting off in second gear, and finding myself pointed in the other direction, I figured "Fuck it", and use it when I can. Hell......There have been times, driving in my car at 10 mph below the posted limit, that my stability control has kicked in due to the lack of traction. Putting the truck in 4 wheel drive is added security in my opinion.
