Harris beach is a big park with different types of camp sites, I stayed in a yurt.  Its also got easy access to the beach.

White Creek has 4 Sites and the privacy isn't great but if you show up early on Thursday and pay 40 dollars a night you can usually get the whole place to yourself.  White Creek has two beaches, one under a beach.  It has a trail that takes you to a cave.  Site 1 is real big with a couple tent spots, and a good hammock spot.  Site 2 has a couple Tent spots.  Site 3 has a couple tent spots.  Site 4 has 1 tent spot.

Steamboat Falls Campground has 9 sites.  it sits 1 mile off of Steamboat road 1 hour outside of Roseburg Oregon.  Site 1 and 2 are on top of each other and should be rented together, which makes it $20 a night but its worth for privacy(To help, 1 has a good view of a water fall).  Site 3 is small and on the road.  Site 4 is huge and definitely the one you want.  It's got room for at least 3 tents and has an amazing view. Site 5 and 6 are good size sites but they don't have much privacy between them, thats another set I usually rent together. Site 7, 8, and 9 have 1 tent pad. There is a day use area with an amazing view, and 2 different trails that takes you to the water.(great swimming and rocks to jump off of)   I will add a video tour of the park.  One negative to this place is Poison Oak, but there are a few signs on the fences showing you what it looks like.
