personal cargo that you add to your trailer
shall not exceed the difference between the
Gross Vehicle Weight Rating (G.V.W.R.) and
this weight. Example: if the G.V.W.R. rating on
the placard is 71 00 Ibs. and the trailer's total
weight is 61 0 0 Ibs., your personal cargo may
not exceed 1000 Ibs. (71 00
-
61 00
=
1000).
The allowable personal cargo, determined
above, must be distributed in your trailer in
such a manner that the Gross Axle Weight
Rating (G.A.W.R.) is not exceeded.
To determine this, it is necessary to load all of
your allowable personal cargo (example above
1000 Ibs. total) and variable weights. Then

page 25.
of the personal cargo must be redistributed
forward in order to place some of this weight on
the tongue.
The tongue weight should be between 10%-
16% of the trailer's weight but must not
exceed 1,000 Ibs. Some tow vehicle
manufacturers may restrict the amount of
tongue load to a lower value. To determine
tongue load, unhitch tow vehicle and place
tongue hitch post on scale, see (3). The trailer
must be properly loaded, as determined above,
with your allowable personal cargo and
variable weights.
Place trailer on scale with both axles only on
scale [see (2) above]. If the weight on the axles
exceeds the axle system G.A.W.R. then some
