Your next step
Sun Lakes-Dry Falls State Park Campground takes rigs up to 50 ft, so what you arrive in decides whether the loop works at all. If you don't own one, the same trip runs on a motorhome rented in Washington.
Nothing in Washington is bookable today — PickRV opens for bookings on October 25. Dated requests are what we take to owners, so give us the window you actually want — you get one email the day a rig covers it, and nothing else.
