First let me tell you, that the 4x4 I drove was bigger than yours. Much bigger. Think 4x4 diesel dually long bed crew cab. This was the truck you'd call to drag your mess out of the ditch. Or the side of a KMart.
I think I know a little about 4x4ing, and you first and foremost don't do it on public roads without compelling reason.
Note: The first snow in recent memory is NOT compelling reason.
