SAE J2807 is an SAE standard for determining the towing capacity of passenger cars, multipurpose passenger vehicles, and trucks. [1] It was written to allow consumers to more accurately compare vehicles from different manufacturers. First released in 2008, it has been periodically updated, with the 2020 version being the most current.
The payload fraction is the quotient of the payload mass and the total vehicle mass at the start of its journey. It is a function of specific impulse, propellant mass fraction and the structural coefficient. In aircraft, loading less than full fuel for shorter trips is standard practice to reduce weight and fuel consumption.

Over time, payload capacities for most domestic pickup trucks have increased while the ton titles have stayed the same. The 1948 Ford F-1 had a Gross Vehicle Weight Rating (GVWR) of 4700 pounds. [24] The truck was marketed with a "Nominal Tonnage Rating: Half-Ton." [24] The actual cargo capacity had increased to 1450 pounds. [24]
A weight-distributing hitch is a "load leveling" hitch. It is a hitch setup mounted on the tow vehicle that uses spring bars and chains under tension to distribute part of the trailer's hitch weight from the towing vehicle's rear axle to the towing vehicle's front axle and to the trailer's axle(s). It can help reduce trailer sway and hop.
The WABCO 3200 was a rare example of a tri-axle haul truck configuration A medium sized haul truck, the 214-short-ton (194 t; 191-long-ton) Caterpillar 789 [1]. Most haul trucks have a two-axle design, but two well-known models from the 1970s, the 350T Terex Titan and 235T WABCO 3200/B, had three axles.
In a spacecraft, the destination is usually an orbit, while for aircraft it is their landing location. A higher mass fraction represents less weight in a design. Another related measure is the payload fraction, which is the fraction of initial weight that is payload. It can be applied to a vehicle, a stage of a vehicle or to a rocket propulsion ...
Towing capacity is a measure describing the upper limit to the weight of a trailer a vehicle can tow and may be expressed in pounds or kilograms. Some countries require that signs indicating the maximum trailer weight (and in some cases, length) be posted on trucks and buses close to the coupling device.
