Rode last night for several hours in about 6 - 8 inches of powder. They do dig in but they are pretty unstoppable in the drifts. 2 wheel drive was usually the travel method but I just had to 4 wheel through some major ditches. Buddies 04' with factory radials was basically skiing everywhere. On dry dirt his top end is a few MPH better than my V2. (I weigh 70 lbs more) Last night I could take him because he was spinning real bad. Top speed in 8 inches of snow 44 mph.
