Looking for input.

Will be taking our first Extended trip (3 weeks) from southern Az. to Southern edge of Yellowstone then up to West Yellowstone and then onto West Glacier.
Can anyone give feedback on the best routes to take or stay away from? My first time at towing a long distance. Will be towing a 37' 5th wheel. I have maped it out so far using google maps. But will also be using Rand McNally Truckers Atlas and my phone. For now I have to consider fuel stops as my TV only has a 29 Gal. tank (F250 diesel). Thanks for your help!!

I am also curious on this as well as I am doing almost the same trip just coming from Michigan instead of AZ.

US-191 is a hard climb going north from Price UT to Duchesne. Same thing between Vernal UT and Flaming Gorge.

Our preferred route is 16 from Evanston - 30 - 89 thru Afton, Alpine and Hoback. Then 191 and spend some time in Jackson and the Elk Refuge area Camping / Fishing. Then north to Yellowstone.
