I don not think so, they're smaller-shorter in size, no hookups. Best if you contact the park ranger direct with a phone call (541) 388-6055

It would have to be REALLY small, and you wouldn't be able to park an additional vehicle. Each specific site states the max vehicle length the parking pad can accommodate when you're making a reservation. They're typically sites that you'd not be able to maneuver more than a small class B/camping van.

Yes, but note the vehicle must fit on the site's pavement and be backed completely into the site. Many tent sites have shorter pads than the RV sites, so if your vehicle doesn't fit, you must select a different site.
