We will be driving from Lewiston, ID to Missoula, MT. The shortest route is Hwy 12. Is this a good route, or is it better to take Hwy 95 up to I95? GMC 2500HD 6.0 with 25 foot TT. Thanks!
Beautiful route..just did this hwy 2 weeks ago from Mt to Wa. Don't be in a hurry. You will most likely average 40mph the whole trip...real curvy. We were not towing but did have our F350 DH was very tired after 200 miles of curves and we will not be towing our 40 footer through there. Go slow be safe.
