East coast trip heading south

Agree with Cherry Hill Park. I would start up in Acadia/Bar Harbor and then work my way south. The southern Maine beaches are awesome (York, Kittery, Ogunquit). There are many quaint towns and villages along the coast. Portsmouth, NH, is a nice, small city with great shops and restaurants as well as Strawberry Banke and the USS Albacore (submarine). Stay at what's now called Spacious Skies campground (was Minuteman) in Littleton MA and explore Boston from there. I don't think Salisbury State Park will be open then. Keep in mind that many campgrounds in the northeast close by Columbus Day weekend. Do NOT take an RV into the city of Boston-the truck will be hard enough to fit. All the outdoor parking that used to exist is now a greenway space. Fall is the best time in New England-apple picking, fairs and festivals abound. All the outdoor parking that used to exist is now a greenway space. Further south you have the beaches in Maryland and the Carolinas. Further south you have the beaches in Maryland and the Carolinas plus the city of Charleston. Further south than that I can't help, other than when you get to Florida. Love the Tampa/St. Pete area. Beaches, museums, etc.
