Favorite cities and states for RVing?

I've been cross country a few times (traveled east to west and back) and enjoyed almost all the states. Due to proximity I visit NY the most. The past two months I have been from Montauk,, Long Island, NY to Niagara Falls, NY. I enjoyed the Finger Lakes,the Catskills (eroded plateau) and the Adirondack Mts. as well as the 1000 Islands region on the St. Lawrence seaway. Several years ago we rented a boat and spent a week on the Erie Canal. It was all very enjoyable. I can't wait to visit the states I haven't seen yet.
