4 36, Total Weight on Your Vehicle s Tires, Hitches, Safety Chains

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/Tire 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.
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 If you’ll be pulling a trailer that, when loaded, will
weigh more than 2,000 lbs. (900 kg), be sure to use a
properly mounted, weight
carrying hitch and sway
control of the proper size. This equipment is very
important for proper vehicle loading and good
handling when you’re driving.
D Will you have to make any holes in the body of your
vehicle when you install a trailer hitch?
If you do, then be sure to seal the holes later when
you remove the hitch. If you don’t seal them, deadly
carbon monoxide (CO) from your exhaust can get
into your vehicle. See “Carbon Monoxide” in the
Index. Dirt and water can, too.
Safety Chains
You should always attach chains between your vehicle and
your trailer. Cross the safety chains under the tongue of the
trailer to help prevent the tongue from contacting the road
if it becomes separated from the hitch. Instructions about
safety chains may be provided by the hitch manufacturer
or by the trailer manufacturer. Follow the manufacturer’s
recommendation for attaching safety chains and do not
attach them to the bumper. Always leave just enough slack
so you can turn with your rig. Never allow safety chains to
drag on the ground.
