200STARTING AND OPERATING
GROSS AXLE WEIGHT RATING (GAWR)
The GAWR is the maximum permissible load
on the front and rear axles. The load must be
distributed in the cargo area so that the GAWR
of each axle is not exceeded.

Each axle GAWR is determined by the
components in the system with the lowest load
carrying capacity (axle, springs, tires or wheels).
Heavier axles or suspension components
sometimes specified by purchasers for increased
durability does not necessarily increase the
vehicle's GVWR.

TIRE SIZE
The tire size on the Vehicle Certification Label
represents the actual tire size on your vehicle.
Replacement tires must be equal to the load
capacity of this tire size.
RIM SIZE
This is the rim size that is appropriate for the tire
size listed.
INFLATION PRESSURE

This is the cold tire inflation pressure for your
vehicle for all loading conditions up to full GAWR.

CURB WEIGHT

The curb weight of a vehicle is defined as the
total weight of the vehicle with all fluids, including
vehicle fuel, at full capacity conditions, and with
no occupants or cargo loaded into the vehicle.
The front and rear curb weight values are
determined by weighing your vehicle on a
commercial scale before any occupants or
cargo are added.

LOADING
The actual total weight and the weight of the
front and rear of your vehicle at the ground can
best be determined by weighing it when it is
loaded and ready for operation.
The entire vehicle should first be weighed on a
commercial scale to ensure that the GVWR has
not been exceeded. The weight on the front and
rear of the vehicle should then be determined
separately to be sure that the load is properly
distributed over the front and rear axles.
Weighing the vehicle may show that the GAWR
of either the front or rear axle has been
exceeded but the total load is within the
specified GVWR. If so, weight must be shifted
from front to rear or rear to front as appropriate
until the specified weight limitations are met. Store the heavier items down low and be sure
that the weight is distributed equally. Stow all
loose items securely before driving.
Improper weight distributions can have an
adverse effect on the way your vehicle steers
and handles and the way the brakes operate.
TRAILER TOWING
In this section you will find safety tips and
information on limits to the type of towing you
can reasonably do with your vehicle. Before
towing a trailer, carefully review this information
to tow your load as efficiently and safely as
possible.
To maintain the New Vehicle Limited Warranty
coverage, follow the requirements and
recommendations in this manual concerning
vehicles used for trailer towing.
CAUTION!

Do not load your vehicle any heavier than the
GVWR or the maximum front and rear GAWR. If
you do, parts on your vehicle can break, or it
can change the way your vehicle handles.
This could cause you to lose control. Also
overloading can shorten the life of your vehicle.

21_DPF_OM_EN_USC_t.book Page 200

STARTING AND OPERATING201
COMMON TOWING DEFINITIONS
The following trailer towing related definitions
will assist you in understanding the following
information:
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your
vehicle. This includes driver, passengers, cargo
and tongue weight. The total load must be
limited so that you do not exceed the GVWR
Úpage 199.
Gross Trailer Weight (GTW)
The GTW is the weight of the trailer plus
the weight of all cargo, consumables and
equipment (permanent or temporary) loaded
in or on the trailer in its "loaded and ready for
operation" condition.
The recommended way to measure GTW is to
put your fully loaded trailer on a vehicle scale.
The entire weight of the trailer must be
supported by the scale.
Gross Combination Weight Rating (GCWR)

The GCWR is the total allowable weight of your
vehicle and trailer when weighed in combination.

Gross Axle Weight Rating (GAWR)

The GAWR is the maximum capacity of the front and
rear axles. Distribute the load over the front and rear
axles evenly. Make sure that you do not exceed
either front or rear GAWR
Ú
page 199.

Tongue Weight (TW)
The TW is the downward force exerted on the
hitch ball by the trailer. You must consider this
as part of the load on your vehicle.
Trailer Frontal Area
The frontal area is the maximum height
multiplied by the maximum width of the front
of a trailer.
Trailer Sway Control (TSC)

The TSC can be a mechanical telescoping link that
can be installed between the hitch receiver and the
trailer tongue that typically provides adjustable
friction associated with the telescoping motion to
dampen any unwanted trailer swaying motions
while traveling.

If equipped, the electronic TSC recognizes a
swaying trailer and automatically applies
individual wheel brakes and/or reduces engine
power to attempt to eliminate the trailer sway.
Weight-Carrying Hitch

A weight-carrying hitch supports the trailer tongue
weight, just as if it were luggage located at a hitch
ball or some other connecting point of the vehicle.
These kinds of hitches are commonly used to tow
small and medium sized trailers.

WARNING!
If the gross trailer weight is 5,000 lbs
(2,267 kg) or more, it is recommended to use
a weight-distributing hitch to ensure stable
handling of your vehicle. If you use a standard
weight-carrying hitch, you could lose control
of your vehicle and cause a collision.
WARNING!
It is important that you do not exceed the
maximum front or rear GAWR. A dangerous
driving condition can result if either rating
is exceeded. You could lose control of the
vehicle and have a collision.

202STARTING AND OPERATING
Weight-Distributing Hitch

A weight-distributing hitch system works by
applying leverage through spring (load) bars.
They are typically used for heavier loads to
distribute trailer tongue weight to the tow
vehicle's front axle and the trailer axle(s). When
used in accordance with the manufacturer's
directions, it provides for a more level ride,
offering more consistent steering and brake
control, thereby enhancing towing safety.
The addition of a friction/hydraulic sway control
also dampens sway caused by traffic and
crosswinds and contributes positively to tow
vehicle and trailer stability. Trailer Sway Control
(TSC) and a weight distributing (load equalizing)
hitch are recommended for heavier Tongue
Weights (TW) and may be required depending
on vehicle and trailer configuration/loading to
comply with GAWR requirements.
Without Weight-Distributing Hitch (Incorrect)With Weight-Distributing Hitch (Correct)
Improper Adjustment Of Weight-Distributing Hitch (Incorrect)
WARNING!
An improperly adjusted weight distributing
hitch system may reduce handling, stability
and braking performance and could result
in a collision.
Weight distributing systems may not be
compatible with surge brake couplers.
Consult with your hitch and trailer manufac -
turer or a reputable Recreational Vehicle
dealer for additional information.

21_DPF_OM_EN_USC_t.book Page 202

STARTING AND OPERATING203
Recommended Distribution Hitch Adjustment

1. Position the truck to be ready to connect to
the trailer (do not connect the trailer).

2. Measure the height of the top of the front wheel opening on the fender to ground, this
is height H1.

Measuring Height (H)

3. Attach the trailer to the vehicle without the weight distribution bars connected.
4. Measure the height of the top of the front wheel opening on the fender to ground, this
is height H2. 5. Install and adjust the tension in the weight
distributing bars per the manufacturers’
recommendations so that the height of the
front fender is approximately (H2-H1)/
2+H1 (about 1/2 the difference between
H2 and H1 above normal ride height [H1]).
6. Perform a visual inspection of the trailer and weight distributing hitch to confirm
manufacturers’ recommendations have
been met.
NOTE:
For all towing conditions, we recommend towing
with TOW/HAUL mode engaged.Fifth-Wheel Hitch
The fifth-wheel hitch is a special high platform
with a coupling that mounts over the rear axle of
the tow vehicle in the truck bed. It connects a
vehicle and fifth-wheel trailer with a coupling
king pin.
Your truck may be equipped with a fifth wheel
hitch option. Refer to the separately provided
fifth wheel hitch safety, care, assembly, and
operating instructions.
Gooseneck Hitch
The gooseneck hitch employs a pivoted
coupling arm which attaches to a ball mounted
in the bed of a pickup truck. The coupling arm
connects to the hitch mounted over the rear
axle in the truck bed.Measurement Example Example 2500/
3500 Height (mm)
