Looking for something else, I happened across the Barlow Jeep School website today.  The school is also on Facebook.

According to the website:

Barlow Jeep School provides professional 4×4 driving instruction and training. Jeeps are our specialty, but all makes of 4wd vehicles are welcome.  Based in Arizona, regular group courses are conducted in the Table Mesa area, north of Phoenix, Arizona. Private, custom training or consultation is available at a variety of locations throughout the western U.S.
