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. Refer to “Vehicle Loading/Vehicle Certification
Label” in “Starting And Operating” for further informa-
tion.
Gross Trailer Weight (GTW)
The GTW is the weight of the trailer plus the weight of all
cargo, consumables and equipment (permanent or tempo-
rary) 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. 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.
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. Refer to “Vehicle Loading/Vehicle Certifica-
tion Label” in “Starting And Operating” for further infor-
mation.
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.404 STARTING AND OPERATING

Tongue Weight (TW)
The tongue weight is the downward force exerted on the
hitch ball by the trailer. You must consider this as part of
the load on your vehicle.
Frontal Area
The frontal area is the maximum height multiplied by the
maximum width of the front of a trailer.
Trailer Sway Control
The 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 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 truck. These kind of hitches
are the most popular on the market today and they are
commonly used to tow small- and medium-sized trailers. Weight-Distributing Hitch
A weight-distributing 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 addi-
tion 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 GAWR require-
ments. 5STARTING AND OPERATING 405

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 manufacturer or a reputable Recreational
Vehicle dealer for additional information.

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 5th wheel hitch option.
Refer to the separately provided 5th 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.Improper Adjustment Of Weight-Distributing Hitch

Trailer Hitch Classification
The following chart provides the industry standard for the
maximum trailer weight a given trailer hitch class can tow
and should be used to assist you in selecting the correct
trailer hitch for your intended towing condition.
Trailer Hitch Classification Definitions
Class Max. Trailer Hitch
Industry Standards
Class I - Light Duty 2,000 lbs (907 kg)
Class II - Medium Duty 3,500 lbs (1,587 kg)
Class III - Heavy Duty 5,000 lbs (2,267 kg)
Class IV - Extra Heavy
Duty 10,000 lbs (4,535 kg)
Fifth Wheel/Gooseneck Greater than 10,000 lbs
(4,535 kg)
Refer to the “Trailer Towing Weights (Maximum Trailer
Weight Ratings)” for the Maximum Gross Trailer
Weight (GTW) towable for your given drivetrain.
All trailer hitches should be professionally installed on
your vehicle. Trailer Towing Weights (Maximum Trailer Weight
Ratings)
NOTE: For additional trailer towing information (maxi-
mum trailer weight ratings) refer to the following website
addresses:

• ramtruck.ca (Canada)
• rambodybuilder.com
Trailer And Tongue Weight
Never exceed the maximum tongue weight stamped on
your trailer hitch or the weights specified in the informa-
tion that can be found under “Trailer Towing Weights
(Maximum Trailer Weight Ratings)”.
Consider the following items when computing the weight
on the rear axle of the vehicle:
• The tongue weight of the trailer
• The weight of any other type of cargo or equipment put
in or on your vehicle
• The weight of the driver and all passengers408 STARTING AND OPERATING

WARNING! (Continued)PARK. For four-wheel drive vehicles, make sure the
transfer case is not in NEUTRAL (N). Always block
or  chock  the trailer wheels.
• GCWR must not be exceeded.
• Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded:
1. GVWR
2. GTW
3. GAWR
4. Tongue weight rating for the trailer hitch utilized.
Towing Requirements — Tires
• Do not attempt to tow a trailer while using a compact
spare tire.
• Proper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle. Refer to
“Tires – General Information” in “Starting And Operat-
ing” for proper tire inflation procedures.
• Check the trailer tires for proper tire inflation pressures
before trailer usage. • Check for signs of tire wear or visible tire damage before
towing a trailer. Refer to “Tires – General Information”
in “Starting And Operating” for the proper inspection
procedure.
• When replacing tires, refer to “Tires – General Informa-
tion” in “Starting And Operating” for proper tire re-
placement procedures. Replacing tires with a higher
load carrying capacity will not increase the vehicle’s
GVWR and GAWR limits.
Towing Requirements — Trailer Brakes
WARNING!• Do not connect trailer brakes to your vehicle’s hy-
draulic brake lines. It can overload your brake sys-
tem and cause it to fail. You might not have brakes
when you need them and could have an accident.
• Towing any trailer will increase your stopping dis-
tance. When towing you should allow for additional
space between your vehicle and the vehicle in front
of you. Failure to do so could result in an accident.410 STARTING AND OPERATING

Snowplow Prep Package Model Availability
For Information about snowplow applications visit
www.ramtrucks.com or refer to the current Ram Body
Builders Guide.
1. The maximum number of occupants in the truck should
not exceed two.
2. The total GVWR or the Front GAWR or the Rear GAWR
should never be exceeded.
3. Cargo capacity will be reduced by the addition of
options or passengers, etc.
The loaded vehicle weight, including the snowplow sys-
tem, all aftermarket accessories, driver, passengers, op-
tions, and cargo, must not exceed either the Gross Vehicle
Weight (GVWR) or Gross Axle Weight (GAWR) ratings.
These weights are specified on the Safety Compliance
Certification Label on the driver’s side door opening.
NOTE: Detach the snowplow when transporting passen-
gers. Vehicle front end wheel alignment was set to specifications
at the factory without consideration for the weight of the
plow. Front end toe-in should be checked and reset if
necessary at the beginning and end of the snowplow
season. This will help prevent uneven tire wear.
The blade should be lowered whenever the vehicle is
parked.
Maintain and operate your vehicle and snowplow equip-
ment following the recommendations provided by the
specific snowplow manufacturer.
Over The Road Operation With Snowplow Attached
The blade restricts air flow to the radiator and causes the
engine to operate at higher than normal temperatures.
Therefore, when transporting the plow, angle the blade
completely and position it as low as road or surface
conditions permit. Do not exceed 40 mph (64 km/h). The
operator should always maintain a safe stopping distance
and allow adequate passing clearance. 5STARTING AND OPERATING 417
