Trailer Towing
Before pulling a trailer, there are
three important considerations that
have to do with weight:
The weight of the trailer
The weight of the trailer tongue
The total weight on the vehicle's
tires

Weight of the Trailer

How heavy can a trailer safely be?
Speed, altitude, road grades,
outside temperature, special
equipment, and the amount of
tongue weight the vehicle can carry
must be considered. See Weight of
the Trailer Tongue later in this
section.
Maximum trailer weight is calculated
assuming only the driver is in the
tow vehicle and it has all the
required trailering equipment. The
weight of additional optional
equipment, passengers and cargo in
the tow vehicle must be subtracted
from the maximum trailer weight.
