Check out The Leisure Seeker: A Novel by Michael Zadoorian. It tells the story of an elderly couple who "run away" in their old camper (Class B or C type)heading from their home in Detroit to Disneyland in CA. Since he has Alzheimer's (he's the driver!!) and she is dying from cancer, you know it is not going to end happily ever after --but along the way it is funny, heart-warming, and a bit of a travelogue as they travel Route 66. One of the best books I have read in some time. It's available in paperback on Amazon and available as an e-book too.
