Thanks for the invite.We plan to do a East Coast trip in a year or so but it will be in the summer or early fall.
I checked out the KOA site and is very nice. I use a web page Called www.vpike.com
If you have a address just type it in and click street view. It will give you a birds eye view. try your home or work address for starters I'm know you'll be impressed. You can zoom and pan even move up and down the street with a bit of practice.
