Cargo Carrying Capacity:
When weighing the motorhome it is important to understand that each motorhome, even of the
same model year, floorplan 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 deter-
mining 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 fluid 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.
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.
