The tongue load can be weighed with a

The tongue load can be adjusted by prop-
er distribution of the load in the trailer.
Never load the trailer with more weight in
the back than in the front; approximately
60 percent of the trailer load should be in
the front and approximately 40 percent in
the rear. Also, distribute the load as even-
ly as possible on both the left and right
sides.
Be sure that all cargo is firmly secured to
prevent a change in weight distribution
while driving.
Trailer hitches
Never drill the frame or under-body
of your vehicle to install a commer-
50% 50%
cial trailer hitch. If you do, danger-
ous exhaust gas, water or mud may
enter the passenger compartment
through the drilled hole. Exhaust
gas contains carbon monoxide, a
colorless and odorless gas which is

dangerous, or even lethal, if inhaled.
Also, drilling the frame or under-
body of your vehicle could cause
deterioration of strength of your ve-
hicle and cause corrosion around
the drilled hole.
Do not modify the vehicle exhaust
system, brake system, or other
systems when installing a hitch or
other trailer towing equipment.
Do not use axle-mounted hitches
as they can cause damage to the
axle housing, wheel bearings,
wheels or tires.
Choose a proper hitch for your vehicle and
trailer.
