LOAD LIMIT
Vehicle Loading - with and
without a Trailer
This section will guide you in the
proper loading of your vehicle,
trailer or both, to keep your loaded
vehicle weight within its design
rating capability, with or without
a trailer. Properly loading your
vehicle will provide maximum
return of vehicle design
performance. Before loading your
vehicle, familiarize yourself with
the following terms for
determining your vehicle
’s weight
ratings, with or without a trailer,
from the vehicle ’s Tire Label or
Safety Compliance Certification
Label:
Base Curb Weight - is the weight
of the vehicle including a full tank
of fuel and all standard
equipment. It does not include
passengers, cargo, or optional
equipment.
Vehicle Curb Weight -
is the
weight of your new vehicle when
you picked it up from your
authorized dealer plus any
aftermarket equipment. Cargo Weight -
includes all
weight added to the Base Curb
Weight, including cargo and
optional equipment. When towing,
trailer tongue load or king pin
weight is also part of cargo weight.
GAW (Gross Axle Weight) -
is
the total weight placed on each
axle (front and rear) including
vehicle curb weight and all
payload. GAWR (Gross Axle Weight
Rating) -
is the maximum
allowable weight that can be
carried by a single axle (front or
rear). These numbers are shown
on the Safety Compliance
Certification Label. The label shall
be affixed to either the door hinge
39

pillar, door-latch post, or the door
edge that meets the door-latch
post, next to the driver's seating
position.
The total load on each
axle must never exceed its Gross Axle Weight Rating.
Note:
For trailer towing
information refer to the RV and
Trailer Towing Guide available at
an authorized dealer. GVW (Gross Vehicle Weight) -
is the Vehicle Curb Weight, plus
cargo, plus passengers.
GVWR (Gross Vehicle Weight
Rating) - is the maximum
allowable weight of the fully
loaded vehicle (including all
options, equipment, passengers
and cargo). It is shown on the Safety Compliance Certification
Label. The label shall be affixed
to either the door hinge pillar,
door-latch post, or the door edge
that meets the door-latch post,
next to the driver's seating
position.
The Gross Vehicle
Weight must never exceed the
Gross Vehicle Weight Rating.

WARNING
Exceeding the Safety
Compliance Certification
Label vehicle weight rating limits
could result in substandard
vehicle handling or performance,
engine, transmission or structural
damage, serious damage to the
vehicle, loss of control and
personal injury. 41
Motorhome (TY3) Canada/United States of America, enUSA, First Printing Load CarryingE198828 E143819GCW
GVW

GCW (Gross Combined Weight)
- is the Gross Vehicle Weight plus
the weight of the fully loaded
trailer.
GCWR (Gross Combined
Weight Rating) - is the maximum
allowable weight of the vehicle
and the loaded trailer, including
all cargo and passengers, that the
vehicle can handle without risking
damage. (Important: The towing
vehicle ’s braking system is rated
for operation at Gross Vehicle
Weight Rating, not at Gross
Combined Weight Rating.)
Separate functional brakes should
be used for safe control of towed
vehicles and for trailers where the
Gross Combined Weight of the
towing vehicle plus the trailer
exceed the Gross Vehicle Weight
Rating of the towing vehicle. The
Gross Combined Weight must
never exceed the Gross
Combined Weight Rating.
Maximum Loaded Trailer
Weight -
is the highest possible
weight of a fully loaded trailer the
vehicle can tow. It assumes a
vehicle with mandatory options,
driver and front passenger weight
(150 pounds [68 kilograms]
each), no cargo weight (internal
or external) and a tongue load of
10– 15% (conventional trailer).
Consult an authorized dealer (or
the RV and Trailer Towing Guide
available at an authorized dealer)
for more detailed information. WARNINGS
Do not exceed the GVWR or
the GAWR specified on the
Safety Compliance Certification
Label. Do not use replacement tires
with lower load carrying
capacities than the original tires
because they may lower the
vehicle ’s GVWR and GAWR
limitations. Replacement tires
with a higher limit than the original
tires do not increase the GVWR
and GAWR limitations. Exceeding any vehicle weight
rating limitation could result
in serious damage to the vehicle
and/or personal injury. Steps for determining the
correct load limit:
1. Determine the combined weight
of the driver and passengers that
will be riding in your vehicle.
2. Subtract the combined weight
of the driver and passengers from
XXX kg or XXX lb.
3. The resulting figure equals the
available amount of cargo and
luggage load capacity. For
example, if the
“XXX” amount
equals 1,400 lb. and there will be
five 150 lb. passengers in your
vehicle, the amount of available
cargo and luggage load capacity
is 650 lb. (1400-750 (5 x 150) =
650 lb.)
42
Motorhome (TY3) Canada/United States of America, enUSA, First Printing Load Carrying

4. Determine the combined weight
of luggage and cargo being loaded
on the vehicle. That weight may
not safely exceed the available
cargo and luggage load capacity
calculated in Step 3.
5. If your vehicle will be towing a
trailer, load from your trailer will
be transferred to your vehicle.
Consult this manual to determine
how this reduces the available
cargo and luggage load capacity
of your vehicle.
The following gives you a few
examples on how to calculate the
available amount of cargo and
luggage load capacity:
*Suppose your vehicle has a
1400-pound (635-kilogram) cargo
and luggage capacity. You decide
to go golfing. Is there enough load
capacity to carry you, four of your
friends and all the golf bags? You
and four friends average 220
pounds (99 kilograms) each and
the golf bags weigh approximately
30 pounds (13.5 kilograms) each.
The calculation would be: 1400 -
(5 x 220) - (5 x 30) = 1400 - 1100
- 150 = 150 pounds. Yes, you have
enough load capacity in your
vehicle to transport four friends
and your golf bags. In metric units,
the calculation would be: 635
kilograms - (5 x 99 kilograms) -
(5 x 13.5 kilograms) = 635 - 495 -
67.5 = 72.5 kilograms.
*Suppose your vehicle has a
1400-pound (635-kilogram) cargo
and luggage capacity. You and
one of your friends decide to pick
up cement from the local home
improvement store to finish that
patio you have been planning for
the past two years. Measuring the
inside of the vehicle with the rear
seat folded down, you have room
for twelve 100-pound
(45-kilogram) bags of cement. Do
you have enough load capacity to
transport the cement to your
home? If you and your friend each
weigh 220 pounds (99 kilograms),
the calculation would be: 1400 -
(2 x 220) - (12 x 100) = 1400 - 440
- 1200 = - 240 pounds. No, you do
not have enough cargo capacity
to carry that much weight. In
metric units, the calculation would
be: 635 kilograms - (2 x 99
kilograms) - (12 x 45 kilograms) =
635 - 198 - 540 = -103 kilograms.
You will need to reduce the load
weight by at least 240 pounds
(104 kilograms). If you remove
three 100-pound (45-kilogram)
cement bags, then the load
calculation would be:1400 - (2 x
220) - (9 x 100) = 1400 - 440 -
900 = 60 pounds. Now you have
the load capacity to transport the
cement and your friend home. In
metric units, the calculation would
be: 635 kilograms - (2 x 99
kilograms) - (9 x 45 kilograms) =
635 - 198 - 405 = 32 kilograms.

The above calculations also
assume that the loads are
positioned in your vehicle in a
manner that does not overload
the Front or the Rear Gross Axle
Weight Rating specified for your
vehicle on the Safety Compliance
Certification Label. The label shall
be affixed to either the door hinge
pillar, door-latch post, or the door
edge that meets the door-latch
post, next to the driver's seating
position.
Special Loading Instructions
for Owners of Pick-up Trucks
and Utility-type Vehicles
WARNING
Loaded vehicles may handle
differently than unloaded
vehicles. Extra precautions, such
as slower speeds and increased
stopping distance, should be
taken when driving a heavily
loaded vehicle. Your vehicle can haul more cargo
and people than most passenger
cars. Depending upon the type
and placement of the load,
hauling cargo and people may
raise the center of gravity of the
vehicle.

TOWING A TRAILER
WARNING
Towing trailers beyond the
maximum recommended
gross trailer weight exceeds the
limit of your vehicle and could
result in engine damage,
transmission damage, structural
damage, loss of vehicle control,
vehicle rollover and personal
injury. Note:
Do not exceed the GVWR or
the GAWR specified on the
certification label. See
Recommended Towing Weights
(page
46).
Your vehicle may have electrical
items, such as fuses or relays,
related to towing. See
Fuses
(page 65).
Your vehicle's load capacity
designation is by weight, not by
volume, so you cannot necessarily
use all available space when
loading a vehicle or trailer.
Towing a trailer places an extra
load on your vehicle's engine,
transmission, axle, brakes, tires
and suspension. Inspect these
components periodically during,
and after, any towing operation. Load Placement
To help minimize how trailer
movement affects your vehicle
when driving:
•
Load the heaviest items closest
to the trailer floor.
• Load the heaviest items
centered between the left and
right side trailer tires.
• Load the heaviest items above
the trailer axles or just slightly
forward toward the trailer
tongue. Do not allow the final
trailer tongue weight to go
above or below 10-15% of the
loaded trailer weight.
• Select a ball mount with the
correct rise or drop. When both
the loaded vehicle and trailer
are connected, the trailer frame
should be level, or slightly
angled down toward your
vehicle, when viewed from the
side.
When driving with a trailer or
payload, a slight takeoff vibration
or shudder may be present due to
the increased payload weight.
Additional information regarding
proper trailer loading and setting
your vehicle up for towing is
located in another chapter of this
manual. See
Load Limit (page
39).
You can also find information in
the
RV & Trailer Towing Guide
available at your authorized
dealer, or online.
