Next, begin to calculate the
Cargo Carrying
Capacity
(CCC)
.
Fresh water weight and LP-Gas weight can
now be subtracted from the remaining total line
A.
Water weight is the number of gallons
multiplied by 8.3.
LP-Gas weight is the number of gallons
multiplied by 4.2.
A 10-gallon water heater with a 40-gallon
fresh tank would total 50 gallons times 8.3, or
415 pounds.
A 30-gallon LP-Gas tank will have 24 gallons
of LP-Gas due to the 80% valve. This would
mean 24 gallons multiplied by 4.2, or 100.8
pounds.
a 15,000 - 415 = B 14,585
B 14,585 - 100.8 = c 14,484.2
Next, calculate the
Sleep Capacity Weight
Rating
(SCWR)
the manufacturer’s designated
number of sleeping positions for the motorhome
multiplied by 154 pounds.
The 154 pounds (70kg) is the average weight
established by the US Federal Government
and Transport Canada, and is used to arrive at
Cargo Carrying Capacity
(CCC)
. However,
actual sleep capacity weight may be greater.
The SCWR is not intended to limit the sleeping
capacity to a specifi ed weight.
Example:
If the manufacturer has designated
the motorhome sleeping position at 4 (616
pounds) and there are four people who weight
200, 200, 178 and 138 pounds, totaling 716
pounds, that doesn’t mean the sleeping capacity
is reduced to three individuals, but rather the
CCC
is reduced by 100 pounds due to the actual
passenger weight.
c 14,484.2 - scWr 716 = ccc 13,768.2
Cargo Carrying Capacity
(CCC)
is how
much cargo the motorhome can carry. However,
tongue weight of a towed vehicle will further
reduce this amount.
Now the motorhome can be fully loaded and
weighed to ensure
GVWR
is not exceeded.
Once the motorhome is fully loaded it is ready
to be weighed to obtain an accurate scale
reading and determine the proper tire pressure.
All slide rooms must be in the retracted position
when weighing the motorhome. The motorhome
must remain as level as possible on the scale,
even when an axle or side is not physically on
the scale.
Each wheel position must be weighed to
accurately determine the weight carried
at each wheel position.
Refer to the previous examples on how
to weigh each wheel position. Each
wheel position weight must be weighed
and recorded to determine proper tire
infl ation.
Wheel position weights are not to exceed
Gross Axle Weight Rating
(GAWR)
and
Gross Vehicle Weight Rating
(
GVWR
)
as printed on the Motorhome Vehicle
Certifi cation Label.
Compare wheel position weights with
weight ratings on the label. If wheel
position weights exceed maximum
specifi cations, items will need to be
removed until rating weight is within
specifi cation.
