VEHICLE PREPARATION
Before beginning an extended trip, ensure you are
thoroughly familiar with your motorhome’s
components, features, appliances and limitations.
Take ample time to read the operator’s manual and
the material in the Motor Information Bag, and
ensure you understand the operation of all the
components.
Adequate preparation is essential for an enjoyable
and successful trip. Your motorhome provides the
freedom to do what you want, where you want, and
when you want. The time you spend getting to know
your motorhome will enhance your enjoyment,
maximize your experience and contribute to a more
successful trip.
KEY CODES
Keep a record of all key code numbers (If equipped)
and keep them in a safe place do NOT keep them in
your motorhome. Key codes for the chassis can be
obtained only through your local authorized Sprinter
dealer.
VEHICLE LOADING AND WEIGHTS
The components of your vehicle are designed to
perform if the motorhome is not loaded in excess of
the Gross Vehicle Weight Rating (GVWR), the
maximum front and rear Gross
Axle Weight Rating (GAWR), or the Gross Combined
Weight Rating (GCWR). These ratings are listed on
the U.S. Department of Transport decals located on
the driver’s seat pedestal behind the skirting.
The GVWR is the maximum permissible weight of the
fully loaded motorhome.
The Unloaded Vehicle Weight (UVW) is the weight of
your motorhome as manufactured at the factory
with full fuel engine oil and coolants.
The Occupant and Cargo Carrying Capacity (OCCC) is
equal to the GVWR, minus UVW, plus full LP gas
weight. In other words, OCCC is the amount of
weight in occupants, cargo, water, and trailer tongue
weight that can be added to the motorhome without
exceeding the GVWR.
The Gross Combination Weight Rating (GCWR) is the
maximum allowable loaded weight of the
motorhome and any towed vehicle.
The Gross Axle Weight Rating (GAWR) is the value
specified as the load carrying capacity of a single axle
system, as measured at the tire- ground interface.
To check that your motorhome is properly loaded,
drive the fully loaded vehicle to a scale and weigh as
follows:
1. Drive only the front wheels onto the scale to
obtain the front gross axle weight.
2. Next, place the entire vehicle (both axles) onto
the scale to obtain the gross vehicle weight.
3. Drive forward until only the rear wheels are on
the scale to obtain the rear gross axle weight.
4. To obtain the corner weight for your
motorhome, drive each tire individually onto the
scale and record the weight.
Compare the gross vehicle weight with the GVWR on
the sticker. If the gross vehicle weight exceeds the
GVWR, you will have to reduce the total vehicle load.
If the gross vehicle weight is less than the GVWR on
the sticker, check the front and rear gross axle
weights against the front and rear GAWRs on the
sticker.
