Great campgrounds everywhere. Just need to find your campground finder tools such as RV Trip Wizard, AllStays Pro, etc. and read the ratings/reviews and see what interests you. Some like high end "resorts" which tend to be parking lots for RV's very close together. I prefer state parks with wide open spaces and a more camping feel of being with nature. Reservations can be tough so book as early as you can once you know where you're going.
