This hill is about 75 yards from the scene of the crime. Picture the view from this driver's seat, facing uphill, nothing but sky. Similar hill/angle, except the downhill side is only one vehicle wide, lined by trees, with a hard break to the left, and much steeper/longer than the gentle downhill shown in this pic.
He was last in a line of 5. Advice on the CB he heard was to stay right. This was in reference to trees on the downhill side... he thought they meant to stay right on the uphill side. By the time he could see the downhill trail, it was too late. The narrow-track CJ on 35s was high right and leaning hard left. Steering neither right nor left could have prevented the roll at that point.
We figure he rolled twice, off to the left side of the trail. The rear of the family cage caught a tree and bounced the rig back to the right, where it was stopped upside-down against a couple other trees.
