Common Towing Definitions
The following trailer towing related definitions will assist
you in understanding the following information.
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your vehicle.
This includes driver, passengers, cargo and trailer tongue

If the gross trailer weight is 3,500 lbs (1 587 kg) or
more, it is mandatory to use a weight-distributing
hitch to ensure stable handling of your vehicle. If
you use a standard weight-carrying hitch, you could
lose control of your vehicle and cause a collision.

The GCWR is the total permissible weight of your vehicle
and trailer when weighed in combination.
NOTE:
The GCWR rating includes a 150 lbs (68 kg)
