Just so you understand my review, I don't think RV camping is camping. It's moving a house around. This guide is really for RV'ers, not for someone like me who wants to camp far away from RV'ers and the noise. I camp using my motorcycle.
Now, setting aside my bias, let me say one thing. WOW. This is a thorough, complete, huge guide. The dead tree version is hard to use (old school though) because there is just so much information. And I find how they organize the states odd. It took a while to figure out where California was located in the guide. Even me, who likes camping away from things, needs to find a more modern campground for showering, washing clothes, connecting to the internet. And this guide is good for that.
But the best thing is the CD which appears to be the whole book on one disk. Now this thing itself should get 10 stars. It's easy to search. It fits in a small area.
So, if you're into car or RV camping, this guide is perfect. If you want to find that secluded primitive campground in the Rockies, this isn't so useful. A solid 5 stars for the finding clean, modern, state of the art campgrounds. A solid 3 stars for those who search for the quiet place.
But that CD is just perfect, which I will carry when I need to find one of those modern campgrounds.
