GMC 2003 GMT560 T-Series, Owner'S Manual, Page: 6 / 284

Model Reference
This manual contains information which covers tilt cab
models as shown. Most models are unfinished from
the factory.
Since T-Series models delivered from the factory are
finished in a variety of ways by a number of companies,
you’ll probably find other manuals in your vehicle.
These manuals are put there by the companies that
have added components or equipment to the T-Series
models. Read all these materials — as well as this
manual — carefully, to get all of the information on
your vehicle.
