Gross Trailer Weight (GTW)

Gross Trailer Weight (GTW) is the total weight under fully-loaded trailer conditions, including food, water, gear, etc. Measure the gross trailer load by placing the fully-loaded trailer on a commercial scale.

Trailer Tongue Weight (TW)

Trailer Tongue Capacity is the downward pressure that the tongue of a fully loaded trailer exerts on the hitch ball. Tongue weight can be measured on a commercial scale, or on a bathroom scale, as illustrated. Be sure the trailer is level and the wheels are chocked.

Vehicle Towing Capacity is the manufacturer's specification of the weight the vehicle is designed to tow. Although some trailer hitches may have a higher stated capacity since they fit other vehicles, never exceed the manufacturer's state trailer capacity. The specifications are found in the vehicle's owner manual, or can be obtained by contacting the vehicle manufacturer.
