Safety Chains - Chevrolet 2008 Colorado Owner's Manual

RGAWR. The effect of tongue weight is about 1.5 times
the actual weight. Dividing the 900 lbs (408 kg) by
1.5 leaves you with being able to handle only 600 lbs
(272 kg) of tongue weight. Since tongue weight is
usually at least 10 percent of total loaded trailer weight,
you can expect that the largest trailer your vehicle
can properly handle is 6,000 lbs (2 721 kg).
It is important that you make sure your vehicle does not
exceed any of its ratings — GCWR, GVWR, RGAWR,
Maximum Trailer Rating or Tongue Weight. The only
way to be sure you are not exceeding any of these
ratings is to weigh your vehicle and 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 located at the bottom of the
center pillar on the driver's side of the vehicle, or see
Loading Your Vehicle on page 4-34. Then be sure
you don't go over the GVWR 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.
Weight-Distributing Hitches and
Weight Carrying Hitches
You can use your step bumper hitch for trailers up to
2,000 lbs (907 kg) total weight, and 200 lbs (90 kg)
tongue weight.
Notice: 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.

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. For trailers up to 2,000 lbs (907 kg) you
may attach the safety chains to the attaching points
on the bumper. For heavier trailers, follow the trailer or
hitch manufacturer's recommendation for attaching
safety chains. Always leave just enough slack so you
can turn with your rig. Never allow safety chains to drag
on the ground.
