Next total both the
+
weight (i.e.
162
Ibs.) and
-
weight (i.e.
22
Ibs.) columns and find the
difference between the two columns; this
becomes ITEM 2 Column B (i.e.
+
140 Ibs.).
Next add ITEM 1 Colurr~n B and ITEM 2
Column B; this becomes ITEM 4 (i.e. 762 Ibs.).
This is the total of your trailer's Factory Tongue
Weight, plus the weight of the Options and
Variable Weights on the tongue. Next enter in
ITEM 5 Column B 12
Y 2
% of your trailer's
G.V.W.R. (i.e. .I25 x 7100
=
887.5), this
information is located on Chart A page 18.
Next subtract ITEM 4 Column B from ITEM 5
Column B and the amount indicates the
amount of Recommended Personal Cargo that
can be added to your trailer's tongue (i.e.
125.5
Ibs.).
The maximum tongue load must not exceed
1000 pounds. Some tow vehicles may restrict
the amount of tongue load to a lower value.
The tongue load is a total of the weight in ITEM
4 Column B plus your personal cargo.
Column C
Column C represents the Maximum Personal
Cargo that can be added to your trailer's axle
system. Find the Factory Axle Weight of your
trailer and enter it in ITEM 1 Column C (i.e.
4069 Ibs.-Factory Axle Weight
=
weight
without options and variable weights). This
information is on Chart A-1 page 18. Next fill in
the axle system weights of the options and
variable weights with which your trailer is
equipped from the Axle System col~rmns on
Chart B or C, page 20, 21. Add all of the
weights together and this total becomes ITEM
2, Colurr~n C (i.e. 692 Ibs.).
Next calculate 34" of ITEM
5 Colurr~n B (i.e.
.34 x 887.5
=
301.75). This becomes ITEM 3
Column C and represents the amount of
tongue weight that is transferred to the trailer's
axle system when properly hitched with a load
equalizing hitch assembly. (The remaining
66% is transferred to the tow vehicle.) Next
add ITEM 1 Cotumn C, ITEM 2 Column C, and
ITEM 3 Column C,; this becomes ITEM 4
Column C (i.e. 5062.75 Ibs.). This is the sum
total of your trailer's Factory Axle Weight, the
weight of the Options and Variable Weights on
the axle system; and 34% of the tongue
weight. Next enter in ITEM 5 Column C, the
sum of your trailer's Gross Axle Weight Rating
(G.A.W.R.-i.e. 3200
+
3200
=
6400 Ibs.).
This information is on the placard on the front
roadside area of your trailer which corresponds
to information on Chart A - l page 18.
The Gross Axle Weight Rating is the maximum
load that can be carried on the axle system
when the trailer is being towed. Next subtract
ITEM 4 Column C from ITEM 5 Column C. The
remainder is the amount of total Maximum
Personal Cargo that can be added to your
trailer's axle system (i.e. 1,337.25 Ibs.).
Under no circumstances shall the G.A.W.R. be
exceeded.
