weight GMC SIERRA 2010 Owner's Guide

The total cargo load must not be more than your
vehicle's CWR.
Refer to the Truck-Camper Loading Information
label in the glove box for dimensions A and B as
shown in the following illustration.
Use the rear edge of the load floor for
measurement purposes. The recommended
location for the cargo center of gravity is at
point C for the CWR. It is the point where the
mass of a body is concentrated and, if suspended
at that point, would balance the front and rear.Here is an example of proper truck and camper
match:
A.Camper Center of Gravity
B.Recommended Center of Gravity
Location Zone
When the truck is used to carry a slide‐in camper,
the total cargo load of the truck consists of the
manufacturer's camper weight figure, the weight of
installed additional camper equipment not
included in the manufacturer's camper weight
figure, the weight of camper cargo, and the weight
of passengers in the camper. The total cargo load
should not exceed the truck's cargo weight rating
5-41

and the camper's center of gravity (A) should fall
within the truck's recommended center of gravity
zone (B) when installed.
You must weigh any accessories or other
equipment that you add to your vehicle. Then,
subtract this extra weight from the CWR. This
extra weight may shorten the center of gravity
zone of your vehicle. Your dealer can help you
with this.
If your slide-in camper and its load weighs less
than the CWR, the center of gravity zone for your
vehicle may be larger.
Your dealer can help you make a good
vehicle-camper match and help you determine
the CWR.
After you have loaded your vehicle and camper,
drive to a weigh station and weigh the front and
rear wheels separately. This will tell you the loads
on the axles. The loads on the front and rear
axles should not be more than either of the Gross
Axle Weight Ratings (GAWR). The total of the
axle loads should not be more than the Gross
Vehicle Weight Rating (GVWR).Open the driver's door and look at the
Certification/Tire label to find out your vehicle's
GAWRs and GVWR.
If your vehicle has gone over the weight ratings,
move or take out some things until all the weight
falls below the ratings.
Secure loose items to prevent weight shifts that
could affect the balance of your vehicle. When the
truck‐camper is loaded, drive to a scale and weigh
on the front and on the rear wheels separately to
determine axle loads. Individual axle loads should
not exceed either of the gross axle weight ratings
(GAWR). The total axle loads should not exceed
your vehicle's gross vehicle weight rating
(GVWR). These ratings are given on the vehicle
certification label attached to the rear edge of the
driver's door. See
“Certification/Tire Label” under
Loading the Vehicle
on page 5‑30. If weight
ratings are exceeded, move or remove items to
bring all weights below the ratings.
5-42

When you install and load your slide-in camper,
check the manufacturer's instructions.
If you want more information on curb weights,
cargo weights, Cargo Weight Rating and the
correct center of gravity zone for your vehicle,
your dealer can help you. Just ask for a copy
of“Consumer Information, Truck-Camper
Loading.”
Pickup Conversion to Chassis Cab
We are aware that some vehicle owners might consider
having the pickup box removed and a commercial or
recreational body installed. Owners should be aware
that, as manufactured, there are differences between
a chassis cab and a pickup with the box removed
which could affect vehicle safety. The components
necessary to adapt a pickup to permit its safe use
with a specialized body should be installed by the
body builder.
Towing
Towing Your Vehicle
To avoid damage, the disabled vehicle should be towed
with all four wheels off the ground. Consult your dealer/
retailer or a professional towing service if the disabled
vehicle must be towed. See Roadside Assistance
Program on page 8‑7.
To tow the vehicle behind another vehicle for
recreational purposes, such as behind a motorhome,
see “Recreational Vehicle Towing” following.
Recreational Vehicle Towing
If the vehicle has a two–mode hybrid engine, see the
Two–mode Hybrid manual for more information.
Recreational vehicle towing means towing the vehicle
behind another vehicle–such as behind a motorhome.
The two most common types of recreational vehicle
towing are known as dinghy towing and dolly towing.
Dinghy towing is towing the vehicle with all four wheels
on the ground. Dolly towing is towing the vehicle with
two wheels on the ground and two wheels up on a
device known as a dolly.
5-43

Towing a Trailer
If the vehicle has a diesel engine, see the DURAMAX®
Diesel manual for more information.
If the vehicle has a two–mode hybrid engine, see the
Two–mode Hybrid manual for more information.
Do not tow a trailer during break‐in. SeeNew Vehicle
Break-In
on page 3‑21for more information.
{WARNING:
The driver can lose control when pulling a trailer if
the correct equipment is not used or the vehicle is
not driven properly. For example, if the trailer is
too heavy, the brakes may not work well or even
at all. The driver and passengers could be
seriously injured. The vehicle may also be
damaged; the resulting repairs would not be
covered by the vehicle warranty. Pull a trailer only
if all the steps in this section have been followed.
Ask your dealer/retailer for advice and information
about towing a trailer with the vehicle. Notice:
Pulling a trailer improperly can damage the
vehicle and result in costly repairs not covered by
the vehicle warranty. To pull a trailer correctly,
follow the advice in this section and see your
dealer/retailer for important information about
towing a trailer with the vehicle.
To identify the trailering capacity of the vehicle, read the
information in “Weight of the Trailer” that appears later
in this section.
Trailering is different than just driving the vehicle by
itself. Trailering means changes in handling,
acceleration, braking, durability and fuel economy.
Successful, safe trailering takes correct equipment, and
it has to be used properly.
The following information has many time-tested,
important trailering tips and safety rules. Many of
these are important for your safety and that of your
passengers. So please read this section carefully before
pulling a trailer.
5-50

Pulling A Trailer
Here are some important points:
.There are many different laws, including speed
limit restrictions, having to do with trailering.
Make sure the rig will be legal, not only where
you live but also where you will be driving.
A good source for this information can be
state or provincial police.
.Consider using a sway control. See“Hitches”later
in this section.
.Do not tow a trailer at all during the first 500 miles
(800 km) the new vehicle is driven. The engine,
axle or other parts could be damaged.
.During the first 500 miles (800 km) that a trailer
is towed, do not drive over 50 mph (80 km/h) and
do not make starts at full throttle. This helps the
engine and other parts of the vehicle wear in
at the heavier loads.
.Vehicles can tow in D (Drive). Shift the
transmission to a lower gear if the transmission
shifts too often under heavy loads and/or hilly
conditions. Important considerations that have to do with weight:
.The weight of the trailer
.The weight of the trailer tongue
.The weight on the vehicle's tires
.And the weight of the trailering combination
Weight of the Trailer
How heavy can a trailer safely be?
It depends on how the rig is used. Speed, altitude, road
grades, outside temperature and how much the vehicle
is used to pull a trailer are all important. It can depend
on any special equipment on the vehicle, and the
amount of tongue weight the vehicle can carry. See
“Weight of the Trailer Tongue”
later in this section for
more information.
Trailer weight rating (TWR) is calculated assuming the
tow vehicle has only the driver but all required trailering
equipment. Weight of additional optional equipment,
passengers and cargo in the tow vehicle must be
subtracted from the trailer weight rating.
Use the following chart to determine how much the
vehicle can weigh, based upon the vehicle model
and options.
Weights listed apply for conventional trailers and
fifth-wheel trailers unless otherwise noted.
