I owned a 4x4 once upon a time. A 1978 Dodge Ramcharger with a 2" lift the PO put on to plow with. It did have the bush bar mounted to the frame which came in handy for when I hit a deer and when I had to create a new trail when I was unable to go back up where we came down.
We beat the ever living snot out of that poor thing.
With the winter tires available now we haven't seen the need to get a 4x4 but in looking at new Durangos they seem to only sell AWD around here. With Blizzaks I was pushing snow with the front bumper last year in the middle of a corn field with only RWD. If it is real bad we just don't go anywhere until the plows get out.
For example like this.
