GENERAL INFORMATION
 An indication of the contents of the motorhome weight label affixed to the motorhome.

A concise explanation of the following items: Vehicle Weight (VW) distribution and Proper
weighing techniques to be used to weigh the vehicle.
 Specific definitions for the following terminology:
Gross Vehicle-Weight Rating (GVWR) – This is the maximum permissible weight of the motor home
when it is fully loaded.
Unloaded Vehicle Weight (UVW) – This is the weight of the motor home, as built at the factory, with
full fuel, engine oil, and coolants. The UVW does not include cargo, fresh water, LP gas, or any dealer-
installed accessories.
Occupant and Cargo-Carrying Capacity (OCC)
– This is the maximum weight of all occupants including
the driver, personal belongings, food, fresh water, waste water, LP gas, tools, tongue weight of towed
vehicle [if any], dealer-installed accessories, and the like. The CCC is equal to or less than the GVWR
minus the UVW.
Gross Combination-Weight Rating (GCWR) – This is the value specified by the chassis manufacturer as
the maximum allowable loaded weight of the motor home with a towed trailer and/or vehicle [if any].
Gross Axle-Weight Rating (GAWR) – This is the maximum allowable weight for an axle; the GAWR
considers the weakest link in the tire, wheel, brakes, hubs, axle, springs, and attaching parts. To
illustrate, if the axle is rated at 15,000 pounds and the tires are rated at 3,200 pounds each as a dual
installation; then the maximum GAWR would be 12,800 pounds for a four-tire vehicle.
WEIGHT PROCEDURES
To weigh the motorhome properly, the motorhome should be level when the weighing process is
performed. Your Wayfarer motorhome has been designed and built in compliance with the
recommended limits of the major-component/system suppliers to provide a realistic CCC. It is up to the
final user to provide even distribution of the loads brought into the motor home to prevent uneven
loading. Once the vehicle is loaded, it can be taken to any certified drive-on scales or individual-wheel
scales to determine that the final weight is within specified limits for the motorhome. The procedure
that can be used is as follows:
First, drive the motorhome onto the scales so that all wheels are on the scales; this provides the gross
vehicle weight (GVW) of the vehicle and can be recorded as such. The GVW should not exceed the
GVWR specified for the vehicle.
