Whats the Gross Trailer Weight (GTW)?
The load of the trailer fully loaded and ready to tow. GTW is found by means of driving the fully loaded trailer onto a vehicle scale. What is the Tongue Weight (TW)? The tongue is the force of the trailer AND the cargo weight behind the rear axle of your tow vehicle. Trailer tongue weight is the downward force pushing on the hitch ball through the trailer coupler. Usually it’s about 10 to 15 % of the GTW. …So the TW (Tongue Weight) = trailer tongue weight + tow vehicle cargo load behind the back axle of your tow vehicle. Figuring the TW for a small trailer: This may be done through the use of a bathroom scale. On a level surface, place the coupler of the loaded trailer on the scale at normal towing height. Weight Distribution Components: In addition to the class III, IV, or V trailer hitch on the vehicle, the weight distribution system is made up of the ballmount, spring bars (a.k.a. load bars or equalizing bars), and trailer mounted brackets. The ballmount is made up of two pieces.
