I do part time RV Transport. I've made 2 runs to Kalispell from Spokane.
My preferred route, to shorten the trip, is I-90 to St Regis, Hwy 135, turn Right on highway 200, then go north on HWY 382, then bear right on HWY 28 which dumps to US93 along Flathead Lake.
My first run I went left on HWY 200 then north on 28. It's a very scneic drive, but it's another climb and descent that wasn't needed, so I came back on 382. Next trip I went on 382 both legs.
Second trip was a big ole (HEAVY) Arctic Fox. I'd do the same route again with any heavy trailer.
