Jeff, don't know where your area is.  I've looked at Texas, New Mexico, and Arizona, all states with numerous public campgrounds (National Parks, State Parks, National Forests, BLM).  None are listed in any of the three states.  This is a  purely commercial compilation from what I can tell, but it does lists lots of RV parks for those who want them.  I'd say it will serve some folks very well, and thanks to Malcolm for posting it.
