Thanks for all of the suggestions. And thanks for the low clearance tunnel heads up on 191. We are around 13'6"!
Taking the suggestions into account-here is my new proposed route: NM-80 to I-10E to Lordsburg. NM-90 to Silver City. US-180 to US-191. Stay on 191 with overnights at St. Johns, AZ, Moab, UT, Rock Springs, WY. Continue on US-191 to Jackson, WY then WY-22/ID-33 to ID-32 to US-20 at Ashton, ID then US-20 to West Yellowstone. I also like to avoid the heavy Interstate traffic and am comfortable driving 2-lane back roads. We've driven US-191 from Bluff, UT to Rock Springs, WY before so am familiar with that part of the drive. Thanks again, comments on the revised route are welcome.
Ugh! I just typed a long one and went to post but it disappeared. :(
So... a shortened version, taking 191 from Globe to Show Low you will not be driving through the tunnel in the above picture. That's on 191 from Clifton to Alpine.
You would only be taking 191 to 70 at Safford, AZ then 70 to Globe then 60 to Show Low. 60 is a downhill of 6 percent into Salt River Canyon and really is not something you should avoid. It's a popular RVing route and semi trucks do it. Just downshift before you start heading down - not in the midst of a downhill. Then after the downhill at the river you'll climb up more gradually to Show Low.
Your alternate plans were to take 191 all the way up to Rock Springs. If you do that north of Vernal, UT is a very steep climb with 10 switchbacks. To me, it's worse than Salt River Canyon.
Instead, take 191 as far as Moab, UT and I-70. Then west on I-70 a short distance to Green River and pick up 6/191 to Wellington to Price and to Duchesne, UT. Then west on 40 to Heber City to Coalville to I-80. Then east on I-80 a short distance to Evanston. Then 16 north to Sage, Wyoming and then north on 30. Don't take 30 to Bear Lake and Garden City. It's steep. Instead, take 30 to Montpelier then 89 north through Thayne and Alpine, Wyoming. Do not continue to Jackson and take 22 to Victor. It's extremely steep and curvy.
At Alpine, head west on 26 - nice and flat along the river - to 31 to Victor and 33 to Idaho 20 north to West Yellowstone. Again, do not get on 22 from Jackson to Victor. You won't like it.
