Towing a Trailer
To achieve a proper tongue load,
start by loading 60 percent of the
load toward the front of the trailer
and 40 percent toward the rear, then
re-adjust the load as needed.
Gross Vehicle Weight Rating
(GVWR):
The maximum allowable weight of
the vehicle, all occupants, all cargo,
and the tongue is:
4,300 Ibs (1,950 kg)
184
Gross Axle Weight Rating
(GAWR):
The maximum allowable weight of
the vehicle axles is:
2,335 Ibs (1,060 kg)
on the front axle
2,030 Ibs (920 kg)
on the rear axle
Checking Loads
The best way to confirm that vehicle
and trailer weights are within limits
is to have them checked at a public
scale.
Using a suitable scale or a special
tongue load gauge, check the tongue
load the first time you set up a
towing combination (a fully-loaded
vehicle and trailer), then recheck the
tongue load whenever the conditions
change.
