Query: Don't buy this book unless you plan to buy Vol. 2

I agree with the fellow who said this book is a bit of bait and switch. Everytime I thought he was going to get into the real details that I wanted, the author just referred to one of his other books. Without Vol. 2 this book will not give you enough information to build a trailer.It does provide some high-level information, and might get you to asking the right questions, but for the price it ought to answer some of those questions. I cannot recommend this book.
