Be sure the trailer is loaded heavier in front, with 60%
to 65% of the weight in front of the axle(s). Loads
balanced over the wheels or heavier in the rear can
cause the trailer to sway severely side to side which
will cause loss of control of vehicle and trailer. Failure
to load trailers heavier in front is the cause of many
trailer accidents. (For a Љ5th WheelЉ style trailer, this
range of loading on the ЉKing PinЉ should be between
15% and 25%.)
•
Make certain that the load is secured in the trailer and
will not shift during travel. When towing cargo such
as livestock, dynamic load shifts can occur that require
the driver to maintain attention.
