There are several spots along Lovell Canyon Rd that you can disperse camp at. If you want to get more than 30 feet off the road then you won't want to do it in an RV, the roads are rough. I came on a Sunday in October and there quite a few people camped along here so grab one of the first that you see. Use the satellite view in Google Maps to find some clearings in the brush. The main road is not very active at night so it's a pretty peaceful sleep.
