Agree. With the properly equipped tow vehicle you will not have any problems with Whitebird or Lewiston hill. The rest of the route is good two lane. Some areas with no to minimal shoulders, but that's about it. A lot of stops on the wide side of the road south of Riggins, for a break. Another climb north of Weiser, and a good rest area on that hill that you can get in and out easily. A downgrade south of New Meadows and north of Cambridge/Council, slow and steady. Open range in that area so be alert.
