I would like to know if anyone has traveled this route. I would kind of like to loop to Idaho Falls to Salt Lake City to Denver. Any advice? We have a 31' Class C and a toad.
it may be a little longer but there are more "big" cities and it's all Interstate (easier drive) if you take I-90 from Gillette, WY to Bozeman, MT
Then Bozeman, MT down to West Yellowstone and West Yellowstone to Idaho Falls. Bozeman to West is a beautiful drive. It follows the Gallatin River and you'll go by Big Sky Ski Resort. Bozeman is also one of the more beautiful cities in MT.
