In case you missed it, there were a couple of good seaside suggestions in the posting
http://www.montanaowners.com/forums/...ad.php?t=59147 I don't have experience with all the parks mentioned but I have stayed at the Winchester Bay RV Park numerous times.
Winchester Bay RV Park is on the Umpqua River just inland of the ocean. Miles and miles of beach shoreline is a short distance away. If you stay on the ocean side of the park (the trailer side), you will have the surf crashing right outside your rear window.
This picture is looking at the RV Park (on the peninsula near the bottom) where the trailer RV spots are on the river side
This is a picture of the park looking west (towards the ocean). The sand dunes start in the upper left hand corner where the river meets the ocean.
