Frontal Area
The Frontal Area is the maximum height and 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're commonly used to tow small- and medium-sized
trailers.
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 direc-
tions, it provides for a more level ride, offering more
consistent steering and brake control and thereby en-
hancing towing safety. The addition of a friction/
hydraulic sway control also dampens sway caused by
traffic and crosswinds, contributing positively to tow
vehicle and trailer stability. Trailer sway control and a
weight distributing (load equalizing) hitch are recom-
mended for heavier Tongue Weights (TW) and may be
required depending
configuration/loading to comply with GAWR require-
ments.
