My WIFE drove the whole thing in a day. Like we left a hotel in the AM and got back to the hotel at night, even after driving through South lake Tahoe and stopping for dinner.If you're careful and took your time you could probably make it through without a scratch. Bumpers sliders and undercarriage are a different story though. Rubicon is pretty epic, we're lucky to be 2-3hrs from the trailhead.
Then you have guys like Nuke - he likes to beat on it like rented mule.
We were solo but there are a bazillion people out there so it's never that sketchy.
