Ordering guide: -- the most detailed information on standard and optional equipment, accessories, and trim packages. You will find out the dealer's "inside information" that is far more detailed than a sales brochure. You'll see prices for trucks, along with prices for options for each RPO code. This book is designed to be used with the data book (for specs and RPO restrictions). Buy now to be one of the few collectors to own this privileged information straight from the showroom floor.
