Up until last week, my DW and I have only stayed at Washington State campgrounds in our relatively new 2720SD. We visited our very first "RV" campground for three days last week. It is called "The Waterfront at Potlatch"
http://www.thewaterfrontatpotlatch.com/ and is located 12 miles north of Shelton on Hwy101 and Hood Canal. Now granted, we do not have the experience to compare it to any other campground but I hope they are all this nice. They have concrete RV pads with full hookups, free cable tv and high-speed wifi, a small motel and individual cabins. All fairly new. Our pad was 30' back and 6' above the beach. Sea Lions, Eagles, Herons, clam and oyster harvesting and a really nice public boat launch right next door. Highly recommended if you are in the area. We enjoyed ourselves so much we attempted to schedule additional time in September but all three of the sites we liked most were booked. Oh well, there is always next summer.......
