I thought I might put some perspective on your trip. When I did the Four Corners some years ago, I visited Ca, WA, ME, and FL. 10,000 Mi in 21 days. That is I averaged 800 KM a day for 21 days. The distances in the US are much greater than in Europe. Also, one piece od advice! Motorcycles in the US are viewed as toys, not real modes of transportation. American drivers don't see them. Not trying to frighten you, just a word of caution. Ride like every driver is figuring out a way to run you over!!
