What is your planned route?? And what are type of site are you going to be looking for: Resort, full hookups, boondocking, or ?.
"North" of Bend there is Sisters City Park, OR State Park at Lake Billy Chinook, Madras, then up to the Gorge on 97 without too many decent sites along the way.
If you are going to go east from Redmond on 26 to 395, there a bunch of nice stops.
Let us know your probable route!!
