A very neat stop in Elkhart, is the Vintage RV Motor-Home Hall of Fame. You can pull up their site, and check them out. They are on the Indy Turnpike. It is a really cool place. You will also be close to Auburn, Indiana. You will need days for that stop ! A.C.D. Museum, and right behind that is the N.A.T.C.O. Truck Museum. As well as the Ford v8 Museum, that is close by. Pull up their sites. Good Luck!
