During the design and development of your motorhome, the number and size of storage
compartments, the liquid tank capacities and the number of designated seating positions are
maximized for value and convenience. If the motorhome operator fills all liquid tanks to capacity,
fills all storage compartments, and cupboards to maximum volume and fills all available,
assigned seating positions with passengers, the motorhome could be overloaded. Please use
the Recreational Vehicle Industry Association's figures shown below to help you determine your
weights.
• Average vehicle occupant
• One gallon of diesel fuel
• One gallon of water
• One gallon of propane
The operator is responsible for analyzing the conditions in which the motorhome will be utilized
for each trip. The number of passengers and placement of cargo can affect the amount of water
capacity that you carry. A smaller passenger capacity for camping provides reasonable cargo
capacity for trips and activities not involving overnight stays. It may be necessary to reduce the
amount of water carried and unload some cargo items normally carried for camping, in order to
provide carrying capacity for the additional day use passengers.
1. Drive the front wheels onto the scale platform and take a reading. This is the front Gross
Axle Weight. (Reading 1).
2. Drive the entire vehicle (all axles) onto the scale and take a reading. This is the Gross
Vehicle Weight. (Reading 2).
3. Drive forward until only the rear axle is on the platform and take a reading. This reading is
the rear Gross Axle Weight. (Reading 3).
4. Compare reading 2 with the GVWR (Gross Vehicle Weight Rating) of your vehicle located
on the Federal Certification Label. If the reading exceeds the GVWR rating, you will have to
reduce the total vehicle load.
5. Check readings 1 and 3 to verify that each is less than the GAWR (Gross Axle Weight
Rating) on the certification label. If either exceeds the GAWR for the axle(s), redistribute
enough of the load to ensure that loads on the front and rear axle(s) are within the
required limit.
or the towed vehicle. Do not exceed the gross combined weight rating of the motorhome. Exceeding any
of these ratings may cause unstable driving and handling characteristics, damage to your motorhome
chassis or towed vehicle and may void your warranty protection.
The following explains commonly used weight abbreviations.
• GROSS VEHICLE WEIGHT RATING (GVWR) is the maximum permissible weight of this
fully loaded motorhome.
• UNLOADED VEHICLE WEIGHT (UVW) is the weight of this motorhome as manufactured
at the factory with full fuel, engine oil, coolants, and propane.
• OCCUPANT and CARGO CARRYING CAPACITY (OCCC) is equal to the GVWR minus
the UVW.
Dealer installed equipment and towed weight will reduce the OCCC.
