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!
We've driven it with our 40' MH. As stated, it's full of curves because of following the river but easily done. If you have a choice, try to drive it during the week. It's a very popular road for campgrounds, fishing, boating, etc. and the weekend is full of adventurers! Have a good trip.
