The weight at the rear axle could be
850 lbs (386 kg) X 1.5 = 1,275 lbs
(578 kg). Since the rear axle already
weighs 2,700 lbs (1 225 kg), adding
1,275 lbs (578 kg) brings the total to
3,975 lbs (1 803 kg). This is very
close to, but within the limit for
RGAWR as well. The vehicle is set to
trailer up to 8,500 lbs (3 856 kg).
If the vehicle has many options and
there is a front seat passenger and
two rear seat passengers with some
luggage and gear in the vehicle as
well, 300 lbs (136 kg) could be
added to the front axle weight and
400 lbs (181 kg) to the rear axle
weight. The vehicle now weighs:
Weight is still below 7,200 lbs
(3 266 kg) and you might think
700 additional pounds (318 kg)
should be subtracted from the
trailering capacity to stay within
GCWR limits. The maximum trailer
would only be 7,800 lbs (3 538 kg).
You may go further and think the
tongue weight should be limited to
less than 1,000 lbs (454 kg) to avoid
exceeding GVWR. But the effect on
the rear axle must still be considered.
Because the rear axle now weighs
3,100 lbs (1 406 kg), 900 lbs
(408 kg) can be put on the rear
axle without exceeding RGAWR.
The effect of tongue weight is about
1.5 times the actual weight. Dividing
the 900 lbs (408 kg) by 1.5 leaves
only 600 lbs (272 kg) of tongue
weight that can be handled. Since
tongue weight is usually at least
10 percent of total loaded trailer
weight, expect that the largest trailer
the vehicle can properly handle is
6,000 lbs (2 721 kg).
It is important that the vehicle
does not exceed any of its
ratings — GCWR, GVWR, RGAWR,
Maximum Trailer Rating or Tongue
Weight. The only way to be sure it is
not exceeding any of these ratings is
to weigh the vehicle and trailer.
Total Weight on the Vehicle’s
Tires
Be sure the vehicle’s tires are
inflated to the upper limit for cold
tires. These numbers can be found
on the Certification label or see
Loading the Vehicle on page 4-28
for more information. Make sure not
to go over the GVW limit for the
vehicle, or the GAWR, including the
weight of the trailer tongue.
