I had a two wheel drive with summer tires and it would get stuck in the rain. I put wrangler work horse tires and about 300lbs in the bed and it would go anywhere I wanted to go in the winter. I now have 4WD and Michelins Summer tread and use 4WD any time it snows. I truly believe tires and driving skill makes it or breaks it. I work for Minnesota DOT as a plow driver and I will tell you the first thing rolled over in the ditch is ALWAYS 4WD! High range should never be used for bad roads, if you need 4wd you should drive according to conditions. It gives unskilled drivers a false sense of security.
