The Federal Certification Label is a guide in knowing the maximum loaded axle weight rating
GAWR
, and subsequently the correct tire inflation pressure for that weight. Every recreational vehicle,
even of the same make and model, will vary in actual loaded axle weights because of different options
and personal loads.
While the actual loaded axle weight should be below the
GAWR
, the motorhome must be weighed
in a loaded condition to determine actual weight. Separately weigh the front and rear axle. It is possible
for a motorhome to be within the
GVWR
yet overloaded on one axle. It is even possible for one wheel
position to be overloaded, even though the
GAWR
has not been exceeded. For this reason it will be
necessary to weigh each wheel position of the motorhome to give a clear indication of exactly how the
weight of the motorhome is distributed.
Instructions and diagrams are presented on the following pages. When the total weight and the weight
on each axle is known, the tire load data chart in this manual will show the correct cold inflation pressure
per tire for each axle.
There are two important factors to consider when loading the motorhome:
total weight
and
balance
.
When loading heavy objects keep them as low as possible, preferably on the floor or below in storage
compartments. Load weight must be distributed as evenly as possible.
The following is an explanation of commonly used weight abbreviations:
•
Gross Vehicle Weight Rating (GVWR):
Maximum permissible weight of this motorhome.
GVWR
is equal to or greater than the sum of
UVW
plus
CCC
.
•
Unloaded Vehicle Weight (UVW):
Weight of this motorhome as built at factory with full
fuel, engine oil and coolants.
UVW
does not include cargo, fresh water, LP-Gas, occupants
or dealer installed accessories.
•
Cargo Carrying Capacity (CCC):
Equal to
GVWR
minus each of the following:
UVW
,
full fresh potable water weight (including water heater), full LP-Gas weight, and
SCWR
.
Tongue weight of towed vehicle and dealer installed equipment will reduce
CCC
.
•
Gross Combination Weight Rating (GCWR):
The maximum allowable loaded weight
of this motorhome and any towed trailer or towed vehicle.
•
Gross Axle Weight Rating (GAWR):
Load-carrying capacity specified by manufacturer
of a single axle system, as measured at tire ground interfaces.
•
Sleeping Capacity Weight Rating (SCWR):
The manufacturer's designated number of
sleeping positions multiplied by 154 pounds.
