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 5,000 lbs. (2 270 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.

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.
Always leave just enough slack so you can turn with your
rig. Never allow safety chains to drag on the ground.

If your trailer weighs more than 2,000 lbs. (900 kg)
loaded, then it needs its own brakes 

--

 and they must be

adequate. Be sure to read and follow the instructions for
the trailer brakes so you’ll be able to install, adjust and
maintain them properly.

Your trailer brake system can tap into the vehicle’s
hydraulic brake system only if:
D The trailer parts can withstand 3,000 psi 

(20 650 kPa) of pressure.

D The trailer’s brake system will use less than 

0.02 cubic inch (0.3 cc) of fluid from your vehicle’s
master cylinder. Otherwise, both braking systems
won’t work well. You could even lose your brakes.

If everything checks out this far, make the brake tap at
the port on the master cylinder that sends the fluid to 
the rear brakes. But don’t use copper tubing for this. 
If you do, it will bend and finally break off. Use steel
brake tubing.
