Have you stayed at this host location?
Okanogan, WA, is very hot and dry in the summer because it's always sunny. We have a reasonably level gravel driveway about 10' X 30' and a garden hose for water; we have no sewer or dump but there's a local dump in town 10 miles away.
We live a good ways out in the countryside and the road, in a couple of places, is a bit "washboard" bumpy. There is a place where a low tow bar will drag and, since there are no trees, there are no low limbs. There is a sharp corner by a fence but it's navigable.
Next to or in front of your rv.
We will usually be home from Easter through Labor Day. We hope to be on the road other times. Give as much notice as you can so we'll be able to be there.
The property is on the Coleville Federation Indian reservation and there really isn't any sightseeing in the area.
