Bulletstuffer, the answer is yes, however! What I observed watching others drive the trails I was driving was that even Toyota 4Runners needed to back up and pull forward on a number of the switchbacks that the Jeep would routinely make in a single pass. The tight turning radius on the Jeep is a major plus on trails like these. I had to back up on pne switch back. The issue here is that when you have to back up on such narrow and steep trails you increase the risk of going off the trail and tumbling to the bottom.
There was an older gent with a lifted Suburban running an outfitting service. He was up on top of one fairly easy to reach pass dropping off back packers. There was another guy in a Chev Avalanch. The wider vehicles have problems on some narrow shelf roads, but as long as you have 4WD and Low Range, decent tires, you can do all but the "difficult" rated trails. I've seen people driving vehicles up there that they should never have left the trail head with. Somehow they usually make it.
Saw one guy in a VW SUV. Not sure the VW model, but it was obvious that this german engineered SUV crossover vehicle really wasn't intended to travel serious roads like this, especially when he nailed the undercarriage a number of times on the rocks. What damage he did to his expensive SUV I don't know. You rarely see Subaru's, Honda's or expensive SUV's on the moderate trails. Jeep wranglers rule, followed by other Jeep models, Toyota mid size trucks and 4 Runners, then a few full sized trucks tossed in.
Ground clearance and a low range are mandatory if youn want to hit any of the passes, Cinamon, Engineer, Stoney, or others.
