If you're using a "dead-weight" hitch, the trailer tongue
(A)
should weigh 10%
of the total loaded trailer weight
(8).
If you have a "weight-distributing" hitch,
the trailer tongue (A) should weigh
12%
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 limit for cold tires. You'll find
these numbers on the Certification Label on the driver's door lock pillar (or
see "Tire-Loading" in the Index). Then be sure you don't go over the GVW
limit for your vehicle.
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:
If you'll be pulling a trailer that, when loaded, will weigh more than 2,000
pounds (900 kg) be sure to use a properly mounted weight-distributing hitch
and sway control of the proper size. This equipment is very important for
proper vehicle loading and good handling when you're driving.
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.
