I'll describe my experience, maybe you can interpolate. I just bought an '08 with 4 wheel drive V-6, but not the center differential type. Had the front raised 2.5" and the rear 1.5" and removed the running boards. Tires are 16" Michelins nearing replacement time, about 57k miles on them. Had a 6" snow the other day and it cruised through it like no snow at all. This morning went out in a fresh 10"+ snow, could tell there was snow, but no problems at all. This was fresh soft snow. I know from experience a crusted snow is a whole different ball game.
I have previously owned Tacomas and learned you could get around OK in fresh 17" of snow but deeper than that significant snow plowing occurred and getting around got a lot tougher; often would have to go until stuck, back up in tracks and take another run in the tracks to plow a few feet further.
I'm curious about the center differential type, why have the two types of 4WD? Is one superior to the other?
