Multiple sites along the creek, some of the road through a wooded area looks dicey for a large vehicle. There are multiple access points to various sites right off of CR306, some look more accessible to regular vehicles. A couple of those access roads seem pretty challenging for a two wheel drive.
The site I camped at was just opposite the road to Avalanche Trailhead. It was a little bumpy but not challenging. All of the sites are within about 100 feet of CR306, separated by woods from the road, very quiet at night.
I camped out in a tent in early October and temps were down in the 30 s at night. Had to keep my heater going. Camped there three nights, really peaceful.
