After seeing your comments I watched a couple of YouTube videos of that last section. To be honest it doesn't -look- that extreme:

We've been down worse in out F350 4WD. That pickup in front of the camera doesn't seem to be a 4WD in this case and the rocks are mainly all flat. And there were no rock steps which are killers for a long vehicle like some Canyonland trails. And there were no several hundred foot drop offs a foot from each side of the vehicle either, like one trail in Capitol Reef. Try the Colorado Rocky trails which have sharp angular rocks, much worse on your tires.
