We flip-flop between all types. We prefer dry FS types where there's room between sites and where most are outdoor nature oriented.
We do stay at W/E at Oregon St parks. We do the RV thing on occasion but usually only when necessary like needing to dump and wash clothes. Or if it's really hot and we need AC. Or if we're on the road and need a stop over for the night.
I do feel that those that are power pole FHU lovers are really missing out on whats out there. I suppose that to some hiking, swimming, bike riding is just not their thing and thats fine. If all I had to do was sit around and stare at my neighbors I wouldn't own an RV.
