We stayed on Piñon for one night this fall. This area has gravel rods and less facilities than the Yucca campground. However, you have large pull in space and more rustic camping. This camp is closer to the entrance and lake for fishing and boating. The sites are basic with electrical and water. The restrooms are basic and no showers. The camp is in a good location to local towns and the highway. This is definitely worth a try.
Lathrop is a desert camp ground that is very open but the sites are just in a row on the road in circles. Just not far in the woods camping. The area does have swimming and boating lakes and walking trails.
