Trailboss, I saw a program on Speed channel not too long ago where Robby Gordon ran a Hummer in the Baha run, I think he won. Now thats heavy. I have to agree with Mark, the D/A combination is so heavy, you wont win any off road races with it if its muddy. I've seen a two wheel drive diesel get stuck in wet grass trying to turn around off the edge of a highway.
