Nearly missed this thread. Inspiring. A few of my off-road spots...
Ophir Pass, CO (told by a Jeep driver I couldn't do it ;-))
Alstrom Pt, Lake Powell...
Up in the Sawtooth Mtns, ID (ATV driver recommended not to go up here!)
Hollister OHV park (not quite stuck, but darn close)...
Big Bend NP (ranger recommended not going down there in a van)...
Castle Valley near Moab...
As you can see I delight in going places people say you can't take vans. But the Quadvan is pretty capable.
I tend to post more to @davecattell on Instagram if anyone is interested.
Dave.
