Advice for a trip up the west coast

Go south on 101 better access to view points and easier to get back on the highway turning right than left! You have a ambitious schedule. The route from Reno via Klamath falls and crossing to Eugene is the easy climb. Go as far north in Oregon on I- 5 as you have time then cut over most roads are fine but the further north the more you climb the “small “ coast range and back down to the sea All very doable but I’ve lived there my whole life and don’t know your comfort level Driving . Now come down 101 . I don’t know where all the switchbacks and close overhangs are but they aren’t on 101 ! ... it’s a major highway ... trucks use highway! 1 maybe in calif but that’s 1 not 101 . The north coast has lots to see and do different from the south coast but you know your timeline. Have a great visit ! Oregon State parks are fantastic and midweek availability can usually be had if you stop early
