We use our truck almost exclusively for towing our toyhauler, which we don't take offroad. It pretty much sits from mid November to around April so we don't worry about the snow. Our other truck is 2WD and it gets driven year round. I've owned 4WD in the past just for the heck of it and have just come to the conclusion that, for me, it's an unnecessary expense and complication. KISS.
The thing that always amazed me was when I was traveling during and after the winter storms around here, that most of the vehicles in the median were 4X4's.
