Last year we stopped for night in Dillan. Ran into a man pulling long bumper pull RV. He suggested we use hy 55/41 from Whitehall to Dillan as it is a lower elevation route. 2 lane but not busy. Thoughts?
MT55/41 climbs slowly southbound. If I remember correctly it is a good two lane highway. I would take it before the interstate just for the scenery and slower pace.
