Weight Columns on Chart B, C or D
Next total both the + weight (i.e. 217 lbs) and
- weight (i.e. 65 lbs)
columns and find the
difference between the two columns; this
becomes ITEM 2 Column B (i.e. + 152 lbs).
Next add ITEM 1 Column B and ITEM 2
Column B; this becomes ITEM 4 (i.e. 642
lbs). 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 12V6% of your
trailer's G.V.W.R. (i.e. .125 x 7100 = 888);
this information is located on Chart A page
20
.
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. 246
lbs).
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.
4545 lbs — Factory Axle Weight = weight
without options and variable weights). This
information is on Chart A page 20. Next fill
in the axle system weights of the options and
variable weights with which your trailer is
equipped from the Axle System columns on
Chart B, C or D pages 21, 22, 23. Add all of
the weights together and this total becomes
ITEM 2, Column C (i.e. 708 lbs).
Next calculate 34% of ITEM 5 Column B (i.e.
.34 x 888 = 302). 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 Column C, ITEM 2
Column C, and ITEM 3 Column C; this
becomes ITEM 4 Column C (i.e. 5555 lbs).
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 lbs).
This information is on the placard on the
front roadside area of your trailer which
corresponds to information on Chart A page
20
.
The Gross Axle Weight Rating is the maxi¬
mum 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. 845
lbs).
Under no circumstances shall the G.A.W.R. be
exceeded.
