Try Durango in Co. and take the train ride to Silverton for a day trip. When leaving Yellowstone, head East across the Big Horns and then south. If your trailer isn't too long and you want to rough it, there are some nice 'boondock' places in the Big Horns - Sitting Bull. Actually Sitting Bull has fairly large sites at 8500 feet, saw a sheep herd drive about 100 yards away from site, and deer slept about 25 feet from one site.
