What is another term for body over frame construction?

Body over frame construction is typically referred to as ladder frame construction. This design involves a separate frame (the "ladder") that supports the body of the vehicle. The frame is made up of two long beams running the length of the vehicle with cross members, resembling a ladder. This structure is particularly common in trucks and larger vehicles, allowing for greater durability and ease of repair, as the body can be easily replaced without affecting the frame.

The term unibody refers to a construction method where the frame and body are combined into a single piece, which is not applicable here. Similarly, monocoque describes a construction where loads are supported by an object's external skin rather than by an internal frame, also different from body over frame construction. Space frame construction involves a structure made from interconnected struts to form a lightweight but strong three-dimensional framework, which again does not match the definition of body over frame construction. Thus, ladder frame is the correct term for this type of vehicle construction.
