Have you ever gone to Potts Mtn?
I met a guy about a year and a half ago who lives in Blacksburg and has run Potts numerous times. I asked if a stock JKU Rubicon could make it. He paused and said he wouldn't recommend it. I then asked about a CJ7 w/ 33" tires and lockers and he said that should do fine.
Myself and a friend were going to do Potts back in Nov, but I had alternator issues with the CJ on the way there. Only got less than halfway before I had to get towed back home.
So the weekend wasn't a complete washout (quite literally, it poured down rain all day Fri) we met up on Sat at Hone Creek campground south west of Harrisonburg. I had the JK with the Ursa Minor for that trip. We ran Union Springs up to Flagpole, then out the southern route towards Reddish. A couple of the ledges that I've never had issue with before had been rutted out. I had to winch over one because of lack of breakover clearance (stock suspension and tire size) and it took some good spotting to get over the 2nd one.
