Our family of four is looking to take a two week RV tour of the Western parks next Summer. Would love to show the kids Yellowstone, the Grand Canyon, Rushmore, maybe some Old West sights. We're on the East Coast so we will probably need to fly out and rent a C-class RV. We prefer to stay in National Park or National Forest campgrounds. We'd like to do some light hiking and would love to see some off the beaten path spots. Any suggestions on an itinerary would be greatly appreciated!
