Ran 21 Road with an old friend from work.  Truck did awesome, the stability is great.  The peace of mind of the axle strength is awesome.  My favorite part has to be the turning radius!  My crawler has never turned so tight!  It's awesome, the combo of detroits along with the hydro assist on a 60 makes this truck completely different.  I've never been happier with the rig.  Only gripe is the diff clearance, huge diffs hang up.  I got a bunch to shave off the rear.  As soon as I learned where the diff was on the front I was able to navigate around most everything.
