Our 26 foot class c had no issues and the dirt road going from the hardball to the sites would be easy for even bigger rvs. There are plenty of turnarounds. The dirt road keeps going for about a mile or two, with sites all along it, eventually splits into two east west running roads, both keep going for about another mile or so with plenty of sites along both. If you go that far up it gets really rocky so I wouldn't recommend and rv. Any campsites along the first 2 miles of the dirt road seem pretty level and big enough for bigger rigs. Passed the fork looks best for 4x4s and tent campers. You can kind of hear sounds from the highway, but at night it's dead quiet. Sites are also spread out enough that you can find a spot without being in direct view of someone's rig
