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/Tire Label located on the B-pillar below the

door latch or see Loading the Vehicle on page 4-33 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. If using a weight distributing hitch, make

sure not to go over the rear axle limit before applying the

weight distribution spring bars.

Hitches

It is important to have the correct hitch equipment.

Crosswinds, large trucks going by and rough roads

are a few reasons why the right hitch is needed.
