You sign on as "USAF wife." Are you or your husband retired military? If so,you are eligible to camp at military Family Camps across the US at military installations. Cost for these, most with full hookups, is usually less than half of what it costs in other campgrounds. There is a website that shows all of them.
There are many communities that have local city- or county-operated campgrounds. My hometown in SW Oklahoma has RV sites with 30/50 amp hookups, water at selected sites and a dump nearby for $5.00 per night.
