Driving and Operating

Here is an example of proper truck and

camper match:

cargo load should not exceed the truck's

cargo weight rating, and the camper's

center of gravity (1) should fall within

the truck's recommended center of

gravity zone (2) when installed.

exceed the vehicle's gross vehicle

weight rating (GVWR). These ratings are

given on the Certification/Tire label

attached to the B-pillar. See

“Certification/Tire Label” under Vehicle

Load Limits 0 204. If weight ratings are

exceeded, move or remove items to

bring all weights below the ratings.

Any accessories or other equipment

that are added to the vehicle must be

weighed. Then, subtract this extra

weight from the CWR. This extra weight

may shorten the center of gravity zone

of the vehicle.

See your dealer for more information

on curb weights, cargo weights, Cargo

Weight Rating, and the correct center of

gravity zone.

If the slide-in camper and its load

weighs less than the CWR, the center of

gravity zone for the vehicle may be

larger.
