Well Damnd,
First off, if you could tell us if you are most interested in:
Scenery,
Real Historic Locations,
Museums - like the in a building kind.
Let me tell you for starters that the price of land in the east coast megopolis if so high, that campgrounds are very rare in striking range of urban centers. (The urban center of the east coast is about 50~150 miles wide inland from where the water touches land. As we have friends all along that area, we have never had to get to a crampground. There really is just one city (look at Google Earth for confirmation) and it stretches along the coast (pretty much I-95) from Portsmouth NH to Petersburg VA. All I can say as a refugee is be ready.
I have always wanted the trip planner that you seek. One that would say,"Hey, you are only an hour's drive from ?????" I haven't found one. The list of places I could suggest would take too long to type. My best suggestion is that you load this route to a AAA trip planner and HANG ON......
When I set up the route in Google Maps, I did notice a shot brain stupid for you. It routes you across New York City. This is something you absolutely do not want to do. Do not try to cross the Hudson any farther south than Nyack-Terrytown (I-287 TappenZee Bridge). Just don't do it. Also, it set you up for a section of Hutchison River Parkway. This is probably bad. Many (most) of the east coast roads that are called "Parkway" only allow passenger cars.
I hope you are aware that the east coast is loaded with history, and there is more than you can absorb in a single pass. I don't care how you plan. You are going to miss things. Just make a list of what you want to not miss the next time.
Be safe. Oh, New York and New Jersey are VERY anti-gun states. NJ has even killed the "Peaceable Transit" idea. Canada allows no hand guns at all, but you can get a permit to carry a long gun. So, be sure you know all the rules before departure.
Matt
