Here is an example of proper truck and camper match:
A. Camper Center of Gravit.y
B. Recommended Center of Gravity Location Zone
The camper's center of gravity should f a l l within the
center of gravity zone for your vehicle's cargo load.
Campers can only be installed in a long box pickup. Check
your Truck-Camper L,oading Label in your glove box to
determine if your vehicle can carry a slide-in camper.
You must weigh any accessories. trailer hitches or other
equipment you add to your vehicle. Then, subtract this
extra weight from the CWR. This extra weight may
shorten the center of gravity zone for your vehicle. Your
dealer can help you with this.
If your slide-in camper and its load weigh 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. He'll also help you determine your CWR.
After you've loaded your vehicle and camper, drive to a
weigh station and weigh on the front and rear wheels
separately. This will tell you the loads on your axles.
The loads on the front and rear axles shouldn't be more
than either o f the GAWRs. The total of the axle loads
should not be more than the GVWR. The GAWR and
GVWR are found on the CertificatiodTire label located
on the driver's door edge, above the door latch.
If you've gone over your weight ratings, move or take
out some things ~ ~ n t i l all the weights fall below the
ratings. Of
C O L I ~ S ~ ,
you should always tie down any
loose items when you load your vehicle or camper.
When you install and load your slide-in camper, check
the manufacturer's instructions.
