Look for low price campgrounds like state parks and corps of engineers parks. They usually have at least water and electric hookups and dump stations. Usually less than $30 per night. If you go to Jellystone, KOA or commercial campgrounds with lots of amenities it can run $100 per night but they do have lots to keep the kids busy. There are some beautiful corps of engineers campgrounds near Bowling Green KY. Look for them on www.recreation.gov I also use www.woodalls.com and www.rvparkreviews.com to locate campgrounds.
