Mike....In Ventura, you have Rincon Parkway which are 40' sites (painted rectangles on the asphalt alongside of the road paralleling the beach) that are anchored at one end by Faria County Park and Emma Woods County Park at the other. Both Faria and Emma Woods are small, dirty and all three are first come first served. During the week (non holiday) you can probably get a site. A little farther north is Gaviota State beach, probably a better choice. Also in that area is a fairly new park called Ocean Mesa, but is pricey.
You'll have to look at a map and do some planning because you're next two stops, Napa and San Francisco are on the west edge of the state and Yosemite is on the east edge of the state, directly across from each other. There are very few RV parks in San Francisco. You'll have to do some research to see how far you're willing to drive. Alcatraz is a great tour, but book tickets in advance.
Depending on what time of the year you're going, Yosemite can be tough to get a campsite. It usually takes booking five months out.
You should have no issues with finding campgrounds in Portland, but Seattle is another place with no campgrounds in town. There is a KOA jut south of Seattle that would probably be your best bet.
