Back from my tip!
It was fantastic. We camped at the only open camp ground at Zion ( Watchman loop B) which was perfect because it had a power hookup. The temps got into the 20's at night and we had a wonderful electric heater.
On the way out I spotted a "OHV" area off the 15. I had to pull off and play!
I was impressed with the traction on these tires (BFG KO2). I could feel the LSD working in the sand. We almost got stuck *only* one time.
The park was near empty during the week, and of course packed during the weekend. My van got a lot of attention and many questions were asked. Met a lot of "van people" who have been traveling around the US in Fords and VWs
Did some great hiking and some relaxing rock climbing
Saw a California Condor in the wild which was spectacular
