External dimensions (LxWxH)
Boot dimensions in working position; usually indicated for open models and boxes (see "Type"). The capacity of the product directly depends on this parameter, in particular, its suitability for transporting large items. And in the case of boxes, dimensions also affect aerodynamics: increasing the height or width increases drag and fuel consumption. At the same time, it should be noted that the aerodynamics of the container also largely depends on its shape.
For open boots, the height is most often not indicated — after all, its actual value usually depends not on the dimensions of the structure, but on the size of the cargo being transported.
Weight
Net weight of the boot in working (fully assembled) form.
The light weight contributes to fuel economy (especially during long-term use) and also makes it easier to transport the boot outside the car (for example, from storage to the car and back). On the other hand, lightening the product leads either to a decrease in its strength and load capacity, or to an increase in cost. So in certain situations, a relatively heavy boot may be the best choice; and when choosing a light model, you should pay special attention to the claimed load capacity.
