Also believe the "horror" stories refer to #1 in California. Do Not take your RV there.
Currently in Newport OR. Started on 101 in Olympia and took 101 north to, and around the Olympic Peninsula, through Ilwaco WA and on south thru' OR to this point. Road is in great condition so far. Most of the "broken pavement" has been repaired. You will have no problems, other than slow driving and lots of traffic - especially on weekend with the current temps on the east side of the Coast Ranges in or close to triple digits driving residents to the coast for the cooler temps.
Good driving and enjoy a great road!
