recommendations for rv campgrounds yellowstone / teton

In 2015, we camped 4 days in Gardiner while we explored the upper loop of Yellowstone, then 4 days in West Yellowstone while we explored the southern loop. We then spent 4 days in Colter Bay RV to see the Grand Teton area before heading home. If at all possible, stop by Cody, Wyoming (east of Yellowstone) and visit the Buffalo Bill Cody Museum---worth the visit. Have a great trip.
