GVWR: The maximum allowable gross weight of the trailer
and its contents. The gross weight of the trailer includes
the weight of the trailer and all of the items within it. GVWR
is sometimes referred to as GTWR (Gross Trailer Weight
Rating), or MGTW (Maximum Gross Trailer Weight). GVWR,
GTWR and MGTW are all the same rating.
The sum total of the GAWR for all trailer axles may be less
than the GVWR for the trailer, because some of the trailer
load is to be carried by the tow vehicle, rather than by the
trailer axle(s). The total weight of the cargo and trailer must
not exceed the GVWR, and the load on an axle must not
exceed its GAWR.
PSIC: The tire pressure (psi) measured when cold.
VIN: The Vehicle Identifi cation Number.
TOW VEHICLE
The towing hitch attached to your tow vehicle must have a
capacity equal to or greater than the load rating of the trailer
you intend to tow. The hitch capacity must also be matched
to the tow vehicle capacity. Your vehicle dealer can provide
and install the proper hitch on your tow vehicle.
SUSPENSION SYSTEM
Sway bars, shock absorbers, heavy duty springs, heavy
duty tires and other suspension components may be
required to suffi ciently tow the trailer and pump.
SIDE VIEW MIRRORS
The size of the trailer that is being towed and your state
law regulations determine the size of the mirrors. However,
some states prohibit extended mirrors on a tow vehicle,
except while a trailer is actually being towed. In this
situation, detachable extended mirrors are necessary.
Check with your dealer or the appropriate state agency
for mirror requirements.
HEAVY DUTY FLASHER
A Heavy Duty Flasher is an electrical component that may
be required when your trailer turn signal lights are attached
to the tow vehicle fl asher circuit.

TRAILER GUIDELINES
ELECTRICAL CONNECTOR
An Electrical Connector connects the lights on the trailer
to the lights on the towing vehicle.
EMERGENCY FLARES AND TRIANGLE REFLECTORS
It is wise to carry these warning devices even if you are
not towing a trailer. It is particularly important to have these
when towing a trailer because the hazard fl ashers of your
towing vehicle will not operate for as long a period of time
when the battery is running both the trailer lights and tow
vehicle lights.
SAFETY CHAINS
If the coupler connection comes loose, the safety chains
can keep the trailer attached to the tow vehicle. With
properly rigged safety chains, it is possible to keep the
tongue of the trailer from digging into the road pavement,
even if the coupler-to-hitch connection comes apart.
JACKSTAND
A device on the trailer that is used to raise and lower the
coupler. The jack is sometimes called the "landing gear" or
the "tongue jack".
COUPLER TYPES
Two types of coupler used with the trailer are discussed
below.
„ Ball Hitch Coupler
„ Pintel Eye Coupler
BALL HITCH COUPLER
A ball hitch coupler (Figure B) connects to a ball that is
located on or under the rear bumper of tow vehicle. This
system of coupling a trailer to a tow vehicle is sometimes
referred to as "bumper pull."
