Next, calculate the
Sleep Capacity Weight
Rating
(SCWR)
the manufacturer’s designated
number of sleeping positions for the motorhome
multiplied by 154 lbs.
The 154 lbs. (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 speci
fi
ed weight.
Example:
If the manufacturer has designated
the motorhome sleeping position at 4 (616 lbs.)
and there are four people who weigh 200, 200,
178 and 138 lbs., totaling 716 lbs., that doesn’t
mean the sleeping capacity is reduced to three
individuals, but rather the
CCC
is reduced by
100 lbs. 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 in
fl
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
Certi
fi
cation Label.
Compare wheel position
weights with weight ratings
on the label. If wheel position
weights exceed maximum
speci
fi
cations, items will need
to be removed until rating
weight is within speci
fi
cation.
