2015 NISSAN Towing Guide 6
5th Wheel or Gooseneck Hitch – Mounted in the bed of a pick-up and designed for heavy-
duty applications, these types of hitches
are not available from NISSAN but can be
purchased from a professional supplier of
towing equipment. At this time, Titan is
the only NISSAN vehicle 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 and is then inserted 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
balls are available in a number of weight capacities and sizes. Most hitch balls have the size

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

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.










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
inflation pressure must be in accordance with the trailer and tire manufacturer’s specifications.
