We have driven the 38 and connect with the 138 to Roseburg a few times and it is a little curvy in spots but definitely RV friendly. It is a beautiful drive.
Our favorite places to stay at Winchester Bay, Newport and Cannon Beach. God willing, we will be spending a month up this later this summer / fall and have two weeks plus at Cannon Beach, a few days at Newport and a week at Bandon - we have not stayed at Bandon before.
Like I said, check out the pix on
www.LaurenBarbara.com and go to OR and Coast and you will see why.
