To determine the available towing capacity,
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 al l
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 ca-
pacity.
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 passengers,
cargo and hitch - 5,073 lb. (2,301 kg).
. Gross Vehicle Weight Rating (GVWR)
from F.M.V.S.S./C.M.V.S.S. certification
label - 5,301 lb. (2,404 kg).
. Gross Combined Weight Rating (GCWR)
from “Towing Load/Specification” chart
- 7,355 lb. (3,336 kg).
. Maximum Trailer towing capacity from
“Towing Load/Specification” chart -
2,000 lb. (907 kg).
5,301 lb. (2,404 kg) GVWR
− 5,073 lb. (2,301 kg) GVW
= 228 lb. (103 kg)
Available for tongue
weight
7,355 lb. (3,336 kg) GCWR
− 5,073 lb. (2,301 kg) GVW
= 2,282 lb. (1,035 kg)
Capacity available for
towing
228 lb. (103 kg) /
Available tongue
weight
2,282 lb. (1,035 kg) Available capacity
= 10 % tongue weight
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 to 15% of the trailer weight. If
the tongue load becomes excessive, re-
arrange the cargo to obtain the proper
tongue load. Do not exceed the 10 to 15%
tongue weight specification even if the
calculated available tongue weight is
greater than 15%. If the calculated tongue
weight is less than 10%, reduce the total
trailer weight to match the available
tongue weight.
Always verify that available capacities are
within the required ratings.
