2. Subtract the actual vehicle weight from the
GCWR. The remaining amount is the avail-
able 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 passengers, cargo
and hitch - 4,926 lb. (2,234 kg) .
.Gross Vehicle Weight Rating (GVWR) from
F.M.V.S.S./C.M.V.S.S. certification label -
5,263 lb. (2,387 kg) .
.Gross Combined Weight Rating (GCWR)
from “Towing Load/Specification” chart -
8,300 lb. (3,765 kg) .
.Maximum Trailer towing capacity from “Tow-
ing Load/Specification” chart - 3,500 lb.
(1,588 kg) .
5,263 lb. (2,387 kg) GVWR
−4,926 lb. (2,234 kg) GVW
= 337 lb. (152 kg)Available for tongue
weight
8,300 lb. (3,765 kg) GCWR
−4,926 lb. (2,234 kg) GVW
= 3,374 lb. (1,530 kg)Capacity available for
towing
337 lb. (152 kg) / Available tongue weight
3,374 lb. (1,530 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 be-
tween 10 to 15% of the trailer weight. If the
tongue load becomes excessive, rearrange the
cargo to obtain the proper tongue load. Do not
exceed the 10 to 15% tongue weight specifica-
tion 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.
