Consider the following example:

A vehicle model base weight is 5,500 lbs (2 495 kg);

2,800 lbs (1 270 kg) at the front axle and 2,700 lbs

(1 225 kg) at the rear axle. It has a GVWR of 7,200 lbs

(3 266 kg), a RGAWR of 4,000 lbs (1 814 kg) and a

GCWR (Gross Combination Weight Rating) of

14,000 lbs (6 350 kg). The trailer rating should be:

Expect tongue weight to be at least 10 percent of trailer

weight (850 lbs (386 kg)) and because the weight is

applied well behind the rear axle, the effect on the rear

axle is greater than just the weight itself, as much as

1.5 times as much. 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.
