GMC 2007 Savana - Manual (Page 276)

Total Weight on Your Vehicle’s Tires
Be sure your vehicle’s tires are inflated to the
upper limit for cold tires. You’ll find these numbers
on the Certification label at the rear edge of the
driver’s door or see Loading Your Vehicle on
page 259. Then be sure you don’t go over
the GVW limit for your vehicle, or the GAWR,
including the weight of the trailer tongue. If you use
a weight distributing hitch, make sure you don’t
go over the rear axle limit before you apply
the weight distribution spring bars.
Hitches
It’s important to have the correct hitch equipment.
Crosswinds, large trucks going by and rough
roads are a few reasons why you’ll need
the right hitch.
The rear bumper on your vehicle is not intended
for hitches. Do not attach rental hitches or
other bumper-type hitches to it. Use only a
frame-mounted hitch that does not attach to the
bumper.
Weight-Distributing Hitches and Weight
Carrying Hitches
When using a weight-distributing hitch, the hitch
must be adjusted so that the distance (A) remains
the same both before and after coupling the
trailer to the tow vehicle.
If you use a step-bumper hitch, your bumper could
be damaged in sharp turns. Make sure you
have ample room when turning to avoid contact
between the trailer and the bumper.
