Ran 21 Road last week.  All went good.  About a foot of snow at the bottom of the trail, made every lil rock a full blown obstacle.  We encountered one obstacle where my buddy in his jeep walked right through but I hung up on for about 20 minutes.  My diff is on the pass side and that screwed me in this particular section.  So I turned the rig around and ran it backwards!  Wahlah, diff on the driver!  Flopped once while showing off, probably a mix of over confidence in the width lol.
