Driving From Coeur D'alene To Sun Valley, Road conditions in Idaho Options

[B Lea]

We are currently in Coeur d'Alene Idaho and want to drive to Sun Valley and Ketchum. We need ad vice on two routes: one would go thru Missoula Montana, then south on Hwy 93, thru Salmon and Stanley, then Hwy 75 south to Sun Valley. The other route would go south on hwy 95 thru Mc Call and Boise, then hwy 20 over to Sun Valley. Both routes have passes and appear to be pretty steep and curvey. We're new RVers and don't want to take on more than we can handle. Those of you who are familiar with the two routes, can you give us advice on which is the best way to go? If both are doable, which has the best scenery? Also, any suggestions on great RV parks along those routes or in Sun Valley?
