Rvpark reviews does NOT list all the CG's available. Doesn't even come close.
I too threw the woodalls GS book out years ago. What a worthless CG book. Same thing only GS sites are listed. And a lot of outdated info.
When I went full time I found the best way to find CG's is to google them in the town you want to stay at.
Google the State and National parks where you want to stay. State and National Parks have the "best' websites. You couldn't ask for more correct and informational info that these sites offer.
I also found the app "Oh Ranger" to be very useful. You are able to search and dial in just what you want the CG to offer.
