Six-Point Weighing Example - Holiday Rambler Imperial 2008 Owner's Manual

DRIVING & SAFETY — 2

Six-Point Weighing Example

The motorhome must be weighed fully
loaded to obtain accurate scale readings and
to determine the proper tire pressure. All slide
rooms must be in the retracted position.
Record the Front Axle Gross Axle
Weight Ratings (GAWR) and divide it
by two. Example: Front Axle GAWR as
listed on the Vehicle Certifi cation Label
is 13,000 lbs. Using the chart, record
6,500 lbs. on Scale A and D, line 1.
Weigh driver side steer axle (Scale A)
and record weight on chart Scale A, line 2.
Example: 5,000 lbs.
Weigh passenger side steer axle (Scale
D) and record weight on chart Scale D,
line 2. Example: 4,000 lbs.
Record the rear axle Gross Axle Weight
Ratings (GAWR) and divide it by two.
44
Example: Rear Axle GAWR as listed on
the Vehicle Certifi cation Label is 20,000
lbs. Using chart below, record 10,000
lbs. on Scale B and E, line 1.
Weigh driver side drive axle (Scale B)
and record weight on chart Scale B, line 2.
Example: 7,100 lbs.
Weigh passenger side drive axle (Scale E)
and record weight on chart Scale E, line
2. Example: 6,900 lbs.
Take the Tag Axle Gross Axle Weight
Rating (GAWR) and divide it by two.
Example: Tag axle GAWR taken from
the Vehicle Certifi cation Label is 10,000
lbs. Using the Six-Point Weighing
Example Chart (on preceding page),
record 5,000 lbs. on Scale C and F, line 1.
Weigh driver side tag axle (Scale C) and
record weight on chart Scale C, line 2.
Example: 4,500 lbs.
Weigh passenger side tag axle (Scale F)
and record weight on chart Scale F, line
2. Example: 4,000 lbs.
2 00 8 I MP E R I A L
Add chart Scale C and F, lines 1, for the
Gross Axle Weight Rating (GAWR)
and record on chart under Totals.
Example: 10,000 lbs.Add chart Scale
C and F, line 2 for actual Gross Axle
Weight (GAW) and record on chart
under Totals. Example: 8,500 lbs.
Actual Gross Axle Weight (GAW).
Example: 8,500 lbs., is not to exceed
Gross Axle Weight Rating (GAWR).
Example: 10,000 lbs.
If necessary, adjust tag axle regulator to
compensate for payload carried by tag,
drive and front axles.
Perform the regulator stabilization
procedure.
NOTE:
Adjustments made to the Tag Axle
Regulator will require repeated
weighing procedures.
If necessary, adjust the payload so the
GAWR is not exceeded. Total combined
weights must not exceed the GVWR.
Refer to the Tire Chart in this section
(the example tire size is 295/80R22.5).
Use the highest actual weight, Scale A
or D, line 2. Example: 5,000 lbs.; Scale
B or E, line 2. Example: 7,100 lbs.;
Scale C or F, line 2. Example: 4,500
lbs. Determine the proper tire pressure
for each axle. Front axle tire pressure is
115 psi, Rear axle tire pressure is 85 psi.
Tag axle tires are 80 psi using the Load
Infl ation chart.
