Don't even have to draw the lines. Because of being in a polarized part of the country and having limited time off, our radius of travel via RV is somewhat small. And, yes, we take the same route every time. I don't like surprises, especially when I'm driving something 12 feet tall, 35 feet long, and dragging a car behind it all!
There are states, especially in the northeast, where it's not necessary to spend the night in order to see a goodly chunk of the state, or even ALL of it.
You can probably add Massachusetts to that list! Although the scenery, terrain and population vary greatly from one end to the other, in less that 3 hours on I90 you can pretty much see it all! The exception is Cape Cod because you have to drive south to get there.
