The roads look fine BUT...... with you time frame I think I would add a number of stops and possibly change some of the routes.
You do plan on seeing GTNP right - possibly Jackson - Wind River Canyon - Cody - Beartooth - Red Lodge - all around the Black Hills and Custer - I could go on and on but you are asking about the routes, IMHO they are fine.
BOL,
Would love to hear more if you have the time.
This is our first extended trip and first to that area. Using Google Earth with Streets & Trips to plan. Would love to know how others figure out their routes & if they can negotiate them. We are in a 32'gas Class A with a Ford Edge toad.
