I also recommend reservations along the Oregon coast. State parks can be booked up to 9 months in advance and pretty much all the popular ones will be booked almost solid Memorial Day to Labor Day. You may find spots here and there, but will be limited.
As for wing_zealot's comment about Walmart parking, along the Oregon coast, there's maybe only a couple Walmarts, not too much in the way of commercialization over there. There may be private campgrounds that can be found, but space is still probably limited.
I don't think Hwy 1 has any WalMarts. :)
OP: You didn't state the size of your RV and if it's long there are sections of Hwy 1 PCH you do not want to be on. Take 101. Park it and use your vehicle to sitesee.
Also, Oregon's state parks on the coast, Cape Blanco at the southern end and Washburne near Florence do not even accept reservations. Plan to be there early the first part of the week and you'll get a site. We did. We love Cape Blanco - rough and wild!
We've also used other Oregon coastal parks without reservations. It can be done but you need to be there in the morning - Beverly Beach, Bullards Beach, Harris Beach, Fort Stevens. We find there are always cancellations.
