We stayed here on the way to Bend.  We got a late start and decided to stop off in Burns, Or., but they were full.  On the advice of a local, we drove the 20+ miles to The Narrows RV Park in Princeton, Or.  It turned out to be a very pleasant diversion as the place had very level spaces, and were wide enough to enjoy.  It had no pool that I am aware of, but did have laundry facilities, a small, but very good cafe and a well stocked store that had of all things 2 buck chuck...except it was 6 bucks.  Also had propane and gas on site...
