Yea out west, water is mucho importante. I looked for a gallon cooler but never found one. I keep trying to put Bear Tooth on the list but, It may end up on a trip to BC, or Yukon.....excuses, excuses.
So after Glacier......

1. Mt Rainer, Wa
2. Mt Hood, Or

6. Black Rock Desert, Nv
7. Great Basin Park, Nv
8. Capitol Reef, Arches, Monument Valley, Ut
9. Hovenweep, Ut
Hovenweep is pretty much out in the middle of nowhere but worth the trip. Keep an eye on fuel. With your auxiliary tank you will be OK. I was OK on my X when I went through there.
My buddy said the Durango/Cortez area has been burning for some time so very smoky. We did not have any problems with smoke on the SE side of Utah last month in my PU.
Monument Valley is one of my favorite. You might give the Mokie Dugway a shot just north of Mexican Hat. It is a bit rough packed dirt/gravel with the hair pins paved. Why paved, I don't know except it makes the gravel kicked on them something to be extra careful of. I made it down on my X and passed two HDs on their way up.
Valley of the Gods is OK but the road is not for our cruisers. I had to pass on it while on my X. I did go back last month in my 4x4 PU. Once is enough. I did not feel the views were worth it.
I accidentally found a neat place to stay right on the San Juan River in Mexican Hat, UT, just north of Monument Valley. It is called the San Juan Inn. Old, small, rasonable, clean, and a good view.
Sounds like you have an awesome full list now. Can't do it all in one trip, I've tried and it nearly killed me. The Beartooth will give you an excuse to plan another ride out west and hit the things you missed on this one.
Always plan ahead for the next trip is my motto. Have a great trip.
