I'm one of the few (many?) who traded-in their 2x4 for a 4x4 evern before I went off-roading. I never knew how fun it would be and I know a lot of owners who have fun with their 2 wheel drives. But for serious/xtreme/insane off-roading, a 4x4 is the choice. Although there are a few insane drivers in a 2x4 having as much fun if not more, than a completely normal driver in a four wheel drive.
