Did you post this on www.rvparkreviews.com? Many people use that website for info on campgrounds. We have fulltimed since 2006 and have only stayed twice in a KOA, just for the reasons you state. Many are poorly maintained and still charge more than a reasonable price. They all have ridiculous add on fees. We stayed in one in West Virginia in 2011, they wanted a $3 fee to give us the gate code if we went out of the campground.
