options required to achieve the rating.
Additional passengers, cargo and/or op-
tional equipment, such as the trailer hitch,
will add weight to the vehicle and reduce
your vehicle’s maximum towing capacity
and trailer tongue load.
The vehicle and trailer need to be
weighed to confirm the vehicle is within
the GVWR, Front GAWR, Rear GAWR, Gross
Combined Weight Rating (GCWR) and
Towing capacity.
All vehicle and trailer weights can be
measured using platform type scales
commonly found at truck stops, highway
weigh stations, building supply centers or
salvage yards.
To determine the available payload capa-
city for tongue/king pin load, use the
following procedure.
1. Locate the GVWR on the F.M.V.S.S./C.
M.V.S.S. certification label.
2. Weigh your vehicle on the scale with
all of the passengers and cargo that
are normally in the vehicle when
towing a trailer.
3. Subtract the actual vehicle weight
from the GVWR. The remaining
amount is the available maximum
tongue/king pin load.
To determine the available towing capa-
city, use the following procedure.
1. Find the GCWR for your vehicle on the
“Towing Load/Specification” chart
found later in this section.
2. Subtract the actual vehicle weight
from the GCWR. The remaining
amount is the available maximum
towing capacity.
To determine the Gross Trailer Weight,
weigh your trailer on a scale with all
equipment and cargo, that are normally
in the trailer when it is towed. Make sure
the Gross trailer weight is not more than
the Gross Trailer Weight Rating shown on
the trailer and is not more than the
calculated available maximum towing
capacity.
Also weigh the front and rear axles on the
scale to make sure the Front Gross Axle
Weight and Rear Gross Axle Weight are
not more than Front Gross Axle Weight
and Rear Gross Axle Weight on the F.M.V.S.
S./C.M.V.S.S. certification label. The cargo
in the trailer and vehicle may need to be
moved or removed to meet the specified
ratings.
Example:
. Gross Vehicle Weight (GVW) as
weighed on a scale - including pas-
sengers, cargo and hitch - 6,350 lb.
(2,880 kg).
. Gross Vehicle Weight Rating (GVWR)
from F.M.V.S.S./C.M.V.S.S. certification
label - 7,250 lb. (3,289 kg).
. Gross Combined Weight Rating
(GCWR) from “Towing Load/Specifica-
tion” chart - 15,100 lb. (6,849 kg).
. Maximum Trailer towing capacity
from “Towing Load/Specification”
chart - 9,100 lb (4,128 kg).

The available towing capacity may be less
than the maximum towing capacity due
to the passenger and cargo load in the
vehicle.
Remember to keep trailer tongue weight
between 10 - 15% of the trailer weight or
within the trailer tongue load specifica-
