Bill;
We haven't decided on our route this year. Last year we basically did Rt 66 to Ca (with stops at GC and Sante Fe), north to SF, Yosemite, Jackson Hole/Tetons, Glacier, Badlands, Oshkosh (Eaa Flyin), back to Stl. (In a Costco tent
).
We missed all of Colorado, Utah, Oregon, Wa. That's what we want to pick up this year, and go back to Yosemite and Glacier if we can. I would not take the trailer on the Going to the Sun highway.
We would park it on one side or the other and just drive our SAV. I know nothing of the Eisenhower Tunnel!! Is this a really scary thing?
