well the Rubicon after last year was about leveled by the Forrestry. I was lucky enough to be there last year before they leveled the little sluice, the old big sluice, the rock and tree squeeze, moved the rock. few years back the leveled the gate keeper. So Now you can do it on 32" no lockers in a subrban. The thing that was odd was other than that tree squeeze. There was go arounds for everything else. I have seen full size pick ups out there.
The group we ran it with from AZ. There was one Jku that only had 33"s no lockers. he made it no dents, excepting under it. So its not like it was now. If you want a test of your rig, Fordyice short but very hard. Or the Dusy longer than the Con and enough rocks lakes and streams to keep the adventure, though the Dusy has very short season. its at a very high elevation. We are going to the Dusy this year and Fordyice the next, maybe.
