2.DETERMINE
THE TOWING WEIGHTS
|
|
The
most important factors in choosing the correct
towing equipment is the gross trailer weight (GTW)
and tongue weight (TW).
|
|
|
|

|
|
|
|
For
the trailer: Gross trailer weight is the weight
of the trailer completely
loaded. To determine actual GTW, the trailer
should be
placed on a vehicle scale.To determine an
approximate GTW, review
the weight chart on Page 105.Select a similar
trailer and find
the corresponding trailer length. The Gross
Trailer Weight provided
is a stock trailer.Adjust the chart weight
accordingly to the
actual load. Tongue
weight (TW) is the downward force exerted on the
hitch ball
by the trailer coupler. Usually, TW is 10% to
15% of GTW. Tongue
weight may be measured using a bathroom scale,
by resting
the trailer coupler on the scale and placing the
scale on a box
so the trailer is at normal towing height.Load
the trailer as if being
towed.
For the tow vehicle: The vehicle’s maximum
towing capacity is determined
by the manufacturer. This is found in the
owner’s manual.

3.SELECTING
THE RIGHT HITCH
|
|
With
the correct Gross Trailer Weight (GTW) and
Vehicle Towing Capacity, the correct trailer
hitch can be selected.Refer to the trailer
weight guide chart ,
to match the GTW to a trailer hitch.
|
|
|
|
Class
I Hidden Hitch is
designed for vehicles towing 2,000 lbs.
|
|
GTW
or less, 200 lbs.TW.In some cases, Class I
Hidden Hitch may tow up to 2,500 lbs. GTW, 250
lbs. TW. A typical Class I application is used
for towing small utility trailers. Passenger
vehicles are most suited for Class I
applications.
|
|
Class
II Hidden Hitch is
designed for vehicles towing 3,500 lbs.
|
|
GTW,
300 lbs.TW.A typical Class II application is
used for towing large utility trailers, boats or
campers. Sport utility vehicles, minivans, large
passenger cars, and mid-size pick-up trucks are
suited for Class II Hidden Hitches
|
|
Class
III & IV Hidden Hitch Receivers have
the towing capacity of up to 6,000 lbs.GTW or
less, 600 lbs TW. The towing capacity may be
increased to a maximum of 10,000 lbs.GTW, 1,000
lbs. TW using a weight distribution system.The
GTW and TW must conform to the vehicles maximum
towing capacity. Refer to the vehicle owner’s
manual. All pick-up trucks, full size vans and
sport utility vehicles may use a Class III
receiver.
|
|
|
|
|
Class
V Hidden Hitch MAGNUM Receivers have
the towing capacity of 8,000 GTW, 1,200
TW;14,000 lbs.GTW, 1,700 lbs.
|
|
TW
with weight distribution.The MAGNUM is designed
for only full-size pick-up trucks.
|

4.SELECT
THE PROPER ACCESSORIES
|
|
Once
the correct trailer hitch is selected, towing
accessories complete the towing package. The
following accessories are required. Several
types of each accessory are available. Consult
the noted page number for exact requirements.
|
|
|
|
|
1.
Trailer
ball - mounted on the drawbar or ball mount.The
ball size must match the trailer coupler size.
|
|
2.
Drawbar/Ball
mount - Hidden Hitch products have removable
ball mounts.
|
|
3.
Trailer
coupler - required on a trailer.
|
|
4.
Electrical and wiring - all tow vehicles must be
properly wired.
|
|
5.
Brake
control - required when towing a trailer with
electric brakes.
|
|
6.
Safety
chains - required when towing.
|
|
7.
Transmission
oil coolers,
a must for all automatic transmissions.

HITCHING
UP TIPS
|
|
Hitching
a trailer to your tow vehicle is usually a
one-man job, but it is easier if someone helps.
|
|
Here
are the basic steps:
|
|
1.
|
Back
your tow vehicle as close as possible to the
trailer;it's easier and safer to do this than to
pull the trailer to your car or truck.
|
|
2.
|
Release
the coupler locking device.
|
|
3.
|
Raise
the front end of the trailer coupler directly
over the hitch ball; then lower it until it is
seated on the hitch ball, covering it
completely.
|
|
4.
|
Check
under the coupling to ensure the ball clamp is
below the ball and not riding on top of it.
|
|
5.
|
Latch
the coupler to the hitch ball. Make sure it's
locked in place by lifting up the trailer
tongue. If the coupler comes loose from the
ball, unlatch it and go back to Step 3.
|
|
6.
|
Make
sure your jack is fully raised.
|
|
7.
|
If
you have a weight-distributing hitch with spring
bars, follow the above procedure, then attach
the spring bar chain to the trailer and tighten
it until your trailer and car are in a normal
level position.
|
|
8.
|
If
your trailer has a surge brake, breakaway cable,
or chain, attach the cable or chain to your tow
vehicle, allowing enough slack for you to make
tight turns.
|
|
9.
|
Attach
the safety chains and criss-cross them under the
ball mount to ensure they do not drag.
|
|
10.
|
Connect
the trailer wiring harness to the lighting
system of your tow vehicle and check its
operation (see the 'Pre-Trip Checklist').
