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 in-
creased durability does not necessarily increase the vehi-
cle’s GVWR.Tire SizeThe tire size on the Label represents the actual tire size on
your vehicle. Replacement tires must be equal to the load
capacity of this tire size.Rim SizeThis is the rim size that is appropriate for the tire size
listed.
Inflation PressureThis is the cold tire inflation pressure for your vehicle for
all loading conditions up to full GAWR.Curb WeightThe 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.LoadingThe 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 commer-
cial scale to insure that the GVWR has not been exceeded.
The weight on the front and rear of the vehicle should
382 STARTING AND OPERATING
Page 385 of 532

then be determined separately to be sure that the load is
properly distributed over front and rear axle. Weighing
the vehicle may show that the GAWR of either the front
or rear axles 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.
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.TRAILER TOWINGIn 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 re-
view this information to tow your load as efficiently and
safely as possible.
To maintain warranty coverage, follow the requirements
and recommendations in this manual concerning ve-
hicles used for trailer towing.

Common Towing DefinitionsThe 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.Gross Trailer Weight (GTW)The GTW is the weight of the trailer plus the weight of all
cargo, consumables and equipment (permanent or tem-
porary) loaded in or on the trailer in itsloaded 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 permissible weight of your vehicle
and trailer when weighed in combination.
NOTE: The GCWR rating includes a 150 lbs (68 kg)
allowance for the presence of a driver.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.
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 an accident.

Tongue Weight (TW)The tongue weight is the downward force exerted on the
hitch ball by the trailer. In most cases it should not be less
than 10% or more than 15% of the trailer load. You must
consider this as part of the load on your vehicle.Frontal AreaThe frontal area is the maximum height and maximum
width of the front of a trailer.Trailer Sway ControlThe trailer sway control is a 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.Weight-Carrying HitchA 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 truck. These kind ofhitches are the most popular on the market today and
they’re commonly used to tow small- and medium-sized
trailers.
Weight-Distributing HitchA weight-distributing system works by applying lever-
age 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 manufacturers’ 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 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 gross
axle weight rating (GAWR) requirements.

WARNING!
•
An improperly adjusted Weight Distributing
Hitch system may reduce handling, stability, brak-
ing performance, and could result in an accident.
•
Weight Distributing Systems may not be compat-
ible with Surge Brake Couplers. Consult with your
hitch and trailer manufacturer or a reputable Rec-
reational Vehicle dealer for additional information.

Fifth-Wheel HitchA special high platform with a coupling that mounts over
the rear axle of the tow vehicle in the truck bed. Connects
a vehicle and fifth-wheel trailer with a coupling king pin.Gooseneck HitchThe 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.Trailer Hitch ClassificationThe rear bumper is intended to tow trailers up to
2,000 lbs (907 kg) without added equipment or alter-
ations to the standard equipment. Your vehicle may be
factory equipped for safe towing of trailers weighing
over 2,000 lbs (907 kg) with the optional Trailer Tow Prep
Package. See your dealer for package content.
The following chart provides the industry standard for
the maximum trailer weight a given trailer hitch class cantow and should be used to assist you in selecting the
correct trailer hitch for your intended towing condition.

Trailer and Tongue WeightAlways load a trailer with 60% to 65% of the weight in
the front of the trailer. This places 10% to 15% of the
Gross Trailer Weight (GTW) on the tow hitch of your
vehicle. Loads balanced over the wheels or heavier in the
rear can cause the trailer to sway severelyside to side
which will cause loss of control of vehicle and trailer.
Failure to load trailers heavier in front is the cause of
many trailer accidents. Never exceed the maximum tongue weight stamped on
your bumper or trailer hitch.
