5th Wheel or Gooseneck Hitch –
A 5th wheel or gooseneck hitch mounts
in the bed of a pick-up and is designed for
heavy-duty applications. A gooseneck
hitch is available from NISSAN for the
Titan. At this time, Titan and Titan XD are
the only NISSAN vehicles approved for
5th wheel and gooseneck trailer towing
.
A 5th wheel or gooseneck hitch is
usually installed and adjusted to meet the
requirements of a particular trailer, but two
basic rules hold true in every case. First,
the hitch should be mounted a minimum
2 inches forward of the rear axle
centerline. Second, it should be securely
attached directly to the truck frame. Only,
professionals should do this installation.

WARNING- It is very important to
mount the hitch correctly to distribute the
king pin load for the proper load carrying
and to control sway. If the trailer sway is
not controlled, it could result in unsafe
vehicle handling which could cause an
accident, property damage, personal injury,
or death.

BALL MOUNT
A ball mount (also known as a drawbar) is a bar that holds a hitch ball, which inserts into a
receiver-type hitch. Ball mounts come in a number of weight capacities (3,500 lbs., 5,000
lbs., etc.) and sizes (1
1/4”, 2”, etc.), and can be
weight distributing or non-weight-distributing.
Choose a proper class ball mount based on
the trailer weight.

HITCH BALL
A hitch ball is bolted through a ball mount or
hitch hole in the tow vehicle’s rear bumper.
The coupler on the trailer tongue attaches
over the hitch ball. Like ball mounts, hitch

2016 NISSAN Towing Guide 7 balls are available in a number of weight capacities and sizes. Most hitch balls have the size
stamped on the top of the ball. The required hitch ball size is stamped on most trailer
couplers. Always make sure the hitch ball selected has the proper shank diameter and weight
rating for the ball mount as well as the coupler on your trailer. Using a 1
7/8” hitch ball in a 2”
coupler, for example, could result in the trailer separating from the tow vehicle.
The diameter of the hitch ball shank must be matched to the ball mount hole diameter. The
shank should be no more than
1/16” smaller than the hole.
To keep the hitch ball in top condition, a simple maintenance routine is recommended.
Coating it with light grease will minimize wear of both the coupler and hitch ball. In addition,
removing the hitch ball when not towing, or protecting it with a special cover will help prevent
rust from forming on it.

TRAILER TONGUE
The tongue is the part of the trailer that extends forward to meet the tow vehicle, and it carries
the coupler assembly. Knowledge of the trailer minimum and maximum tongue load
(conventional trailers) and king pin load (5th wheel and gooseneck trailers) is critical as it can
have a significant effect on the handling and capacity of the tow vehicle. Refer to your vehicle
owner’s manual to view the maximum conventional trailer tongue load listed for your vehicle.
Trailer tongue weight is the amount of downward pressure exerted onto the hitch ball. Keep
the tongue load between 10-15% of the total trailer weight. DO NOT exceed the maximum
tongue load specification. If the tongue weight is below the recommended amount, you must
move some of the load forward or add weight to the front frame of the trailer.

SAFETY CHAINS/CABLES
Always use suitable safety chains/cables
between the tow vehicle and the trailer. If the
hitch should break or become disengaged
while towing, these chains/cables will help
provide an emergency connection between
the vehicle and the trailer.
When installed properly the chains/cables
should be crossed under the trailer tongue,
and attached to the hitch or vehicle frame.
Crossing the chains/cables under the tongue
will help prevent the tongue from hitting the
ground should the trailer become
disconnected. Be sure to leave enough slack
in the chains/cables to turn corners without
binding; however, note that excessive slack
will allow the chains/cables to drag on the
ground.

For example, to determine the proper trailer tongue load for a 1,500-lb. trailer, multiply the
weight of 1,500 lbs. by 10% to arrive at a figure of 150 lbs. 5th wheel and gooseneck trailer
king pin load must be kept between 15-25% of the actual trailer weight, within the limits of
the king pin load allowable.
Some trailer types may require different trailer tongue loads for safe towing. Always follow
the trailer manufacturer’s recommendations for proper trailer set-up and trailer tongue load.
Keep the trailer tongue load within the maximum trailer tongue load allowable. Additionally,
make sure the vehicle has the payload capacity available for the trailer tongue load.
Refer to your vehicle owner’s manual to view the maximum conventional trailer tongue load
listed for your vehicle.
WARNING – DO NOT exceed any of the individual vehicle weight ratings (GVWR,
GAWR, GCWR, etc.), regardless of trailer or hitch type. Overloading or improper
loading of a trailer can cause unsafe vehicle handling, braking and performance and may
lead to a serious accident and personal injury or death.










HITCH & TRAILER HEIGHT
It is important that your trailer floor and tongue ride as level as possible. This will help prevent
over-angling, bottoming-out, and improper tongue load and load transfer. Therefore, the hitch
or trailer tongue must be adjusted during the initial vehicle/trailer fit-up to ensure a level ride.
Ball mounts are available in different configurations to adjust the hitch ball height.

TIRE PRESSURE
When towing a trailer, ensure that the tow vehicle’s tire pressures are inflated to the
recommended cold tire specification. You will find these figures in the vehicle owner’s manual
and on the tire pressure chart located in the vehicle. Trailer tire condition, size, load rating, and
tire pressure must be in accordance with the trailer and tire manufacturer’s specifications.

GROSS COMBINED
WEIGHT RATING (GCWR) The maximum allowable combined weight of the vehicle and trailer,
including passengers and all cargo.
GROSS VEHICLE
WEIGHT RATING (GVWR) The maximum allowable weight of the vehicle, including passengers, cargo,
fuel, hitch, trailer tongue load, and any optional equipment.
KING PIN
LOAD The amount of trailer (5th wheel or gooseneck) weight pressing down on the
tow vehicle hitch.
HITCH BALL
A ball that connects the trailer to the tow vehicle hitch that provides the
means by which the trailer pivots during cornering. Available in a number
of sizes and weight capacities, it must correspond to the trailer coupler
size, and have a sufficient capacity rating for the trailer being pulled.

RECEIVER HITCH A frame- or structure-mounted hitch with a receiver that allows removal of
the ball mount.

SAFETY CHAINS/CABLES Provides an emergency connection between the tow vehicle and the trailer,
should the trailer become disengaged for any reason.

SURGE BRAKES
Hydraulic-type braking system activated by inertia. As the tow vehicle
begins to brake, the trailer pushes against the hitch ball, consequently
activating the trailer brakes.

TRAILER TONGUE/COUPLER The part of the trailer that extends forward to meet the tow vehicle, and
carries the coupler assembly.

TRAILER TONGUE
LOAD The amount of trailer (conventional) weight pressing down on the tow
vehicle hitch.

WEIGHT-DISTRIBUTING
HITCH SYSTEM Type of hitch system that helps shift the trailer tongue weight to all trailer
tires and the tow vehicle front tires. Strongly recommended when towing
trailers with a Maximum Trailer Weight greater than 5,000 lbs.

WIRING HARNESS Provides an electrical connection linking the tow vehicle’s electrical system
to the trailer’s system.
