Hey Porky! How's it going with your trip?
I've done a lot of Internet searching on this subject. I was looking for more a campground type park rather than a luxury motorcoach type park. So scratch the Outdoor Resorts park in Newport, OR. Some parks that looked possible:
Latitude 49 RV Resort near Bellingham, WA. Here is a lot that just sold there. http://www.rvonline.com/campgrounds/081ct001.html
Park also has website.
Coastal Marina RV Park near Florence OR. I drove past this small park but couldn't see much. It is right on the river with nice views. Here is a lot for sale. http://www.rvonline.com/campgrounds/cg208.html
Safari Campground, Ilwaco WA. Nice area. http://www.safaricampground.com/index.htm
Skookum Rendezvous RV Park, Newport (Spokane) WA. I really liked the location of this park and was serious about it but in the end, not campgroundish enough for me and good sites taken. It is on the beautiful Pend Oreille River. http://www.skookum-rendezvous.com/
That's the best of what I could find. I did not know about Lake Merwin Campers Hideway. The website doenst seem to be working. I would like to see pics of the park. How much?
