jquest000, I don't quite agree. Yes when going up hill most of the weight is on the back, but most of us have posi. It's when one tire is in the air the posi fails. It's easier to keep the rear in contact with the ground than the front. True the front isn't as strong. When on flat trails the weight is on the front, with one front tire off the ground the rear has to push the front over the obsticle( like a 2wheeldrive) until both front tires have traction. On a straight axle front end I would agree though.
