I can't speak for 95 all the way from Boise, but we came south down Hwy 55 from McCall a few years back and it was a beautiful drive. Lots of curves following a river and railway, but a good wide roadway. There weren't any bad grades along it. There is a great state park in McCall named Ponderosa State Park with very good hookups if you are looking for a spot about half way.
Hwy 95 from McCall to Lewiston is more of the same, not a bad drive. Hwy 95 north of Lewiston is a bear though. There is about five miles of 7% uphill grade if you are going northbound. We were coming down the grade and there were runaway truck ramps about every 3/4 mile. It will test your grade brake.
