I lived in NY for a number of years, and most of their parkways are not RV friendly and are marked as such. It might be that heading into the campground/state park you're good. I'm 13'2" with the 5th wheel, so I won't chance it...until after I drive with and confirm lol.
Great advice on the campgrounds - I'll check out both the KOA and the State Parks. I've really been wanting to try a state park - we have the generator, and so even if we had minimal hookups, we'd be fine (though I've never dry camped and I'm scared to death of it lol).
Thanks for the inputs!
