If Oregon appeals to you then why not, it is certainly on my "to do list" and very scenic but most States have great drives, scenery and National parks. You could start out in Salt lake City or Portland for instance and loop through Oregon, but you could also start and finish in many places as well as LA, San Fran, Las Vegas, Denver could also be options.
You really need to sit down with a good map and look around the forums to see what really appeals to you and get some dots on the map and work it out from there. In the "Roadtrip field reports" section you will find 2 of my previous RV trips, one starting from San Fran, the other Denver that will show possibilities but there are options just about everywhere.
Once you get it figured let us know and we can help to "fine tune" your trip.
