There are a ton of campsites here, and even more options if you have a high clearance vehicle. 

If you have a low clearance RV I recommend taking the first road to the left after crossing the cattle guard. That road leads around most of the camping area and you can avoid the side roads with the steep entrances. 

It is right next to a landfill which is interesting but there were no flies or smells in October. 

For a free camping area right next to a city the area felt safe and was surprisingly clean.
