Ha! I knew I would find you on here eventually...
One month is really quick. Do you have certain spots that you want to see?
The Lost Coast, Usal Road. That's a great trip, although conditions change drastically after any rains. Coming from the south you enter north of Fort Bragg and you can go all the way to Ferndale. Great drive. Although I couldn't comment on sportsmobile clearances since I drove a Landcruiser through there last time...
Oregon has some of the best state parks around for camping. Especially when it comes to location, cleanliness, and price.
Eastern Oregon has a BUNCH of areas to explore. They have actually mapped out a road that goes from the CA/OR border to the OR/WA border. I have the maps for this route if you want to borrow them some time.
