Original 1986 GMC Trucks Dealer Data Book. This Sales Reference Book covers the Medium Duty Truck models. These were used by Sales Staff to educate themselves on the Truck Models and to help Customers make their purchase. It highlights the features, options, pricing and specifications for the Medium Duty Models. It also includes the Vocational E-Z Specs to aid in ordering new Trucks. This Data Book is in an incorrect GMC Truck Colors & Trim Binder. The enclosed Data Book appears to be complete and is in good condition with minor wear, soiling and blemishing [see photos]. Very rare and informative Dealer Only item that will display well.
