Add-On Equipment
When you carry removable items, you may need to put
a limit on how many people you carry inside your
vehicle. Be sure to weigh your vehicle before you buy
and install the new equipment.
Notice: Overloading your vehicle may cause
damage. Repairs would not be covered by your
warranty. Do not overload your vehicle.
Remember not to exceed the Gross Axle Weight
Rating (GAWR) of the front or rear axle.
*Equipment Maximum Weight
Ladder Rack and Cargo 750 lbs (340 kg)
Cross Toolbox and Cargo 400 lbs (181 kg)
Side Boxes and Cargo 250 lbs per side
(113 kg per side)
*The combined weight for all rail-mounted equipment
should not exceed 1,000 lbs (454 kg). A reinforcement
kit for rail-mounted add-on equiupment is

Truck-Camper Loading Information
This label is inside your glove box. It will tell you if
your vehicle can carry a slide-in camper, how much of a
load your vehicle can carry, and how to correctly
spread out your load. Also, it will help you match the
right slide-in camper to your vehicle.
When you carry a slide-in camper, the total cargo load
of your vehicle is the weight of the camper, plus
•
everything else added to the camper after it left the
factory,
•
everything in the camper and
•
all the people inside.
The Cargo Weight Rating (CWR) is the maximum
weight of the load your vehicle can carry. It doesn’t
include the weight of the people inside. But, you
can figure about 150 lbs (68 kg) for each seat.
The total cargo load must not be more than your
vehicle’s CWR.
Refer to the Truck-Camper Loading Information label in
glove box for dimensions A and B as shown in the
following illustration.
