I would pick I-90 to Butte MT and south. All you can do is 511 for weather and check Dot web sites. You may just get slowed by weather but just hunker down when it gets bad. I would winterize MH and carry bottled water and rv antifreeze to flush toilet. I would have tire chains for MH. I always carry them even if I will never need them.
Ah NO
This add's lets see... Ryegrass summit, 4th of July Pass, Lookout Pass and Monida Pass, crossing lots more mountain ranges.
It does take out the Dead-man pass (I-84) and going over Manastash Ridge (I-82), but they are lower passes then Lookout and Monida...
...and it's lots longer.
I've also done the I-5 to Portland, but that adds 5 hours to the trip (I only do it when I-90 is closed).
I-90 to I-82 to I-84 to I-15 is the simplest route and the one I usually take.
Coming back is less fun, and the west-bound (down) grade on Deadman/Cabbage is not fun
