STARTING AND OPERATING
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.
Frontal Area
The frontal area is the maximum height
multiplied by the maximum width of the front of
a trailer.
Trailer Sway Control (TSC) – If Equipped
The TSC is a telescoping link that can be
installed between the hitch receiver and the
trailer tongue. It 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 vehicle. These kinds of hitches are
commonly used to tow small and medium sized
trailers.
Weight-Distributing Hitch
A weight-distributing hitch 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 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, 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.
