A box truck, also known as a cube van or a box van, is a type of commercial vehicle characterized by its enclosed cargo area. It's essentially a truck chassis with an attached box-shaped cargo compartment, which provides protection and security for transported goods. Box trucks are commonly used for local and regional deliveries, moving services, and other tasks that require the transport of items that need to be shielded from the elements.

The dimensions of a box truck can vary based on the specific model and manufacturer, but in the USA, the general dimensions for box trucks are as follows:

Length: Typically ranges from about 10 feet (3.05 meters) for smaller models to around 26 feet (7.92 meters) for larger models.
Width: Approximately 7 to 8 feet (2.13 to 2.44 meters), similar to the width of a standard lane on a road.
Height: Usually falls within the range of 10 to 13 feet (3.05 to 3.96 meters), again depending on the size and design of the box truck.

Box trucks come in various weight classes, and their payload capacity can vary accordingly. They are often categorized based on their Gross Vehicle Weight Rating (GVWR), which indicates the maximum weight a vehicle can carry, including its own weight. Common GVWR classes for box trucks include Class 3 (10,001 to 14,000 pounds), Class 4 (14,001 to 16,000 pounds), and Class 5 (16,001 to 19,500 pounds), among others.

The box or cargo area of a box truck is typically accessed through rear doors, although some models might also have side doors for easier loading and unloading. The cargo area can be customized with shelving, tie-downs, and other features to suit specific transportation needs.

Box trucks are a staple in the logistics and transportation industry due to their versatility and ability to protect cargo from the elements. They are commonly used for local deliveries, moving household goods, transporting small to medium-sized items, and even serving as mobile workshops or retail units.

As with any commercial vehicle, it's important for box truck operators to be aware of weight limits, size restrictions, and other regulations that apply to their specific region or route.
