I think the last few posts are key. You have to look at hotel rates. I've stayed in Hampton Inns for 25 years. Usually good, clean, safe, and a decent (and improving) breakfast. I've gone from $60/night to $120, more than that is a city.
I love the KOA in Queechee Pines, VT. I think in the neighborhood of $60/night in the fall. Location, location, location. I can take day tours to northern or southern Vermont to chase peak. Good local smoke house next door. Decent campstore and friendly workers.
I've stayed on concrete pads that weren't level. Most level site I've ever stayed on was limestone lots that were in an independent campground in South Dakota that was built around the annual motorcycle rally.
