Gross Trailer Weight

(GTW) The Gross Trailer Weight is the weight of the trailer & cargo. You can measure this by putting the fully loaded trailer on a vehicle scale.

G.T.W. - Determine trailer, cargo weight for towing

Tongue Weight

(TW) The downward force that is exerted on the hitch ball by the coupler. The tongue weight will vary depending on where the load is positioned in relationship to the trailer axle(s). To measure the tongue weight, use either a commercial scale or a bathroom scale with the coupler at towing height. When using a bathroom scale with heavier tongue weights, use the method shown and multiply the scale reading by 3.

Weight Carrying

(WC) The total weight of both the trailer and the cargo inside. Never exceed the weight capacity of your trailer hitch.

Hitch Selection Guide

Use this table to select the correct class of hitch for your vehicle. Refer to not only vehicle type, but also the trailer(s) that you will be towing. See the CURT Hitch Application Guide to the Left.
