If you’re using your platform hitch as a weight
-
carrying
hitch, the trailer tongue (A) should weigh 10 percent of
the total loaded trailer weight (B). If you’re using your
platform hitch as a weight
-
distributing hitch, the trailer
tongue (A) should weigh 12 percent of the total loaded
trailer weight (B).
After you’ve loaded your trailer, weigh the trailer and
then the tongue, separately, to see if the weights are
proper. If they aren’t, you may be able to get them right
simply by moving some items around in the trailer.
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 “Tire Loading” in the Index. Then be sure you 
don’t go over the GVW limit for your vehicle, including
the weight of the trailer tongue.
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. Here are
some rules to follow:
D The bumpers on your vehicle are not intended 
for hitches. Do not attach rental hitches or other
bumper
-
type hitches to them. Use only a
frame
-
mounted hitch that does not attach to the
bumper. Do not use a ball hitch, because it could 
pull the bumper loose.
