We have stayed 16 years in a row at South Jetty, Pacific City, La Conner for 7 weeks each summer. I see no reason for 50 amp sites as you seldom need AC on the Coast. I have never needed full hookups in the 36 years as a TT Member. There are sites for large RVs at each one of the above Parks. I love that we get to pick our own sites several years ago South Jetty assigned sites. Several years ago I towed my 40 ft 5th w to the above Parks in July and Aug and disconnected and drove around to find a big enough site. Worked for me. I downsized to 32 ft TT as I did have problems with branches scrapping the top of the 5th w. That is one reason I went back to TT plus the extra steps in the 5th w. That is hard on 79 yr old hips, knees etc
