Joshua Tree National Park there are some back in spaces at the west camp ground and there is a "pull trough" at the top of the camp ground, there are showers and toilets no hook ups there is a dump at the bottom of the camp ground, call ahead to the park and ask the rangers, we spent a few Christmas's, it can be very windy.
Back in sites seem to be fairly level, some of the other ones are a challenge to level the RV, they do have hours when the generator can be turned on for breakfast, lunch and dinner, other wise it is quiet!
