Cal,
That definitely looks like a GoSlow road in your pic above ... it appears plenty wide enough though. We once had to go around 7 MPH for 25 miles each way in our little Class C, but nothing fell off the walls and everything still worked while camping out there and after we got back.
Which of the four areas included in the Parashant is that photo from? Being National Monument areas now, probably one can't get anywhere near them in a powered vehicle. Pretty soon only young folks with good legs and a decent body mass index will be able to get near Nature's ultimate beauty here in the U.S..
