Without seeing the program your talking about, I can't tell you anything about it. But I have collected the books or web site info the organizations have made available. The books and other info is nice to have but often contain errors. So what I did was put together my own list. And it takes some time. The way that I put a list together was searching online. There are several resources for this. One of the best is rvparkreviews, just plug in the state you're interested in their search bar and presto; you'll find many of them. Not all. Go thru the state you'll interested in. Then change the organization and go the states again.
As far as the books or web site info the organizations produce.
