RV parking over night along PCH?

I'd be willing to bet most of those pictures that you see are either the earlier reference Rincon Park spots or staged events with proper permits and road closure to ensure safety. From what I remember of the PCH, there are pull-offs where you can make lunch and take in the amazing views. I doubt you could set up camp though.

I'm a little envious that you are going to make that drive. It is truly a gorgeous and wonderful drive. Lots of amazing bridges, spectacular views and wonderful places for side trips. I hope you enjoy your trip. That is on our "retirement trip" list!!!
