General Trailering Notes Where available, the Trailering Package (Z82) provides a
trailer hitch platform and a 7-pin sealed connector at the rear bumper. A 7-wire
camper/fifth-wheel wiring harness (UY2) is also available and requires the Trailering
Package (Z82).
Automatic Transmission Note Automatic transmissions are equipped with an engine
oil cooler (KC4) and an oil-to-air transmission oil cooler (KNP).
Trailer Tongue Weight Notes Trailer tongue weight should be 10–15% of total loaded
trailer weight for conventional towing. The addition of trailer tongue weight must
not cause vehicle to exceed Rear Gross Axle Weight Rating (RGAWR) or Gross Vehicle
Weight Rating (GVWR).
Gooseneck/5th-Wheel Kingpin Weight Notes Gooseneck or fifth-wheel kingpin
weight should be 15–25% of the total loaded trailer weight. The addition of trailer
kingpin weight cannot cause vehicle to exceed Rear Gross Axle Weight Rating
(RGAWR) or Gross Vehicle Weight Rating (GVWR). These ratings can be found on the
certification label located on the driver door or doorframe. A fifth-wheel hitch is
offered on specific models and is also available as a dealer-installed accessory on
select models. See the Trailering Basics on page 7 for more trailering information.

Gooseneck/5th-Wheel Trailering Notes Silverado HD can be equipped with a
gooseneck or fifth-wheel trailer hitch. Follow the manufacturer's directions for
installation, but note that the hitch must be attached to the truck frame. Do not use
the pickup bed for additional support. For proper kingpin tongue load distribution and
control of the trailer, the hitch must be mounted so the kingpin load is placed near the
rear axle centerline. Fifth-wheel trailer kingpin loads are higher than conventional
trailer tongue loads, so pay careful attention to the truck's payload capacity and Rear
Gross Axle Weight Rating (RGAWR). Your Chevrolet dealer can help you calculate the
maximum allowable payload and GVWR required for your fifth-wheel trailering
application. The weight of any additional equipment and all passengers must be
subtracted from the payload weight to determine the maximum kingpin load available.
Gooseneck/5th Wheel Prep Package The Gooseneck/5th Wheel Prep Package
(Z6A) includes a hitch platform ready to accept a gooseneck ball or fifth-wheel
5
hitch, a box-mounted trailer harness, a spray-on bedliner, and all the necessary box
and bedliner holes drilled and capped.
