We recommend loading the trailer in
such a manner that it has a tongue
weight (TW) between 10% and 15% of
the GTW.
Checking weights of vehicle and trailer
To assure that the tow vehicle and trail-
er are in compliance with the maximum
permissible weight limits have the load-
ed rig (tow vehicle including driver, pas-
sengers and cargo, trailer fully loaded)
weighed on a commercial scale.
Check the vehicle's front and rear
Gross Axle Weight (GAW), the GTW and
TW.
The values as measures must not
exceed the weight limits listed under
