Cargo Carrying Capacity:
When weighing the motorhome it is important to understand that each motorhome, even of the same model
year, fl oorplan and length will weigh different due to options and accessories. The Gross Vehicle Weight Rating
(GVWR), Gross Combination Weight Rating (GCWR) and/or Gross Axle Weight Rating (GAWR) must not be
exceeded.
GVWR of the vehicle limits the weight of the entire load combination, regardless of the water, LP-Gas,
passengers and cargo weight.
It is important to understand that the weighing process is performed in two phases. First, by determining
the Cargo Carrying Capacity (CCC); and second, to ensure the GVWR is not exceeded when adjusting tire
pressures. The weighing process should start by recording the GVWR from the Federal Weight Label, then
weighing the motorhome unloaded, without passengers and with a full fuel tank. Engine and transmission fl uid
levels must be full. This is known as the Unloaded Vehicle Weight (UVW). Once this weight has been recorded it
can be subtracted from the GVWR.
GVWR
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 lbs.
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 lbs.
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. (70 kg.) 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 lbs.) and there are
four people who weight 200, 200, 178 and 138 lbs., totaling 716 lbs., that does not 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
Cargo Carrying Capacity (CCC) is how much cargo the motorhome can carry. However, tongue weight of a
towed vehicle will further reduce this amount.
