Ok the only thing I found re the traveling conditions is:
Our nightly stops in churches and community centers also provide great opportunities for us to share our experiences with our gracious hosts.
Back to the big question, any vehicular support? How good is the best mechanic? If I were doing this with the crowd I toured with a couple of times it would be no problem. One of the guys rebuilt a wheel for me after a pothole hit where the local shop could not. But if you don't have that kind of person in hte group and no support you could be in big trouble. Also if carrying everything that is one more thing you have to get used to.
