Sounds like a great trip! Suggestions will vary, depending on how much time you are allowing for the trip. (I hope you're allowing at least a month!) I would suggest making a list of those sights in the U.S. you have always wanted to see but never have, and try to include them on the itinerary if possible. Plan your routes accordingly. When do you leave? If it's soon, be aware that many CGs in the northern tier won't be open until at least April 1st, and a good number not even until May. The idea of buying a camper (I'd go used, to minimize your loss) rather than renting, is a good one, IMO. And if you like it, you may just want to keep it & use it for camping trips in the East after you get settled. Good luck!
