We just completed a caravan through Cody, West Yellowstone and Jackson ( Tetons) We did go through Rapid City and visited Mt Rushmore and Crazy Horse before heading to Cody. We went through Yellowstone via the east gate to the west gate. We stayed at a park right past the KOA about 8 miles outside West Yellowstone, for the life of me I can't remember the name of the park. After Yellowstone we traveled to Jackson Hole through Yellowstone and out the south gate. We drive a 38' coach towing a GMC Arcadia, and had no problems what so ever. It is definetly a worthwhile trip, very beautiful. Have fun and be safe.
