First of all, to answer your question, the American military standard requires a load of more than 660 pounds (299? Kg), after the three companies submitted the prototype, the US military chose the "Willis Four Wheels" of Willis-Ovlando Automobile Company as the standard model. After improvement, "Willys Quad" became "MA" and later "MB" Willis MB often runs around with more than twice the designed goods in actual use, and even puts on steel wheels to drag the train carriages. Because it is a wartime military vehicle, it is not overloaded and is not allowed to go on the road. Equipped with 22 1 1 ml engine, the Willis MB with a maximum power of 44 kW (60 HP) can basically be loaded and pulled. Therefore, the car only has a minimum requirement of 299KG and no standard load.
In addition, the jeep is not a truck, and the load is not a hard indicator. If you buy a BMW X5/20 17 SUV today, you can only see the vehicle's own weight and no load in the parameters.
There are two figures in the production quantity column of Willys MB in the table. The former is a jeep produced by Willis-Ovlando Automobile Company, and the latter is authorized by Ford Company. M38 and M38A 1 are from the 1950s. Although the shape is similar, it is a completely different jeep design.
