True or False: A full-frame vehicle has a body that is a part of the main frame.

In the case of a full-frame vehicle, it is characterized by having a separate body and frame structure. The frame serves as the primary support for the vehicle, while the body is mounted on top of the frame. This design allows for easier repairs and modifications, as the body can be removed independently of the frame.

In contrast, a unibody vehicle integrates the body and frame into a single structure, which is common in most modern cars for efficiency and weight reduction. Therefore, stating that a full-frame vehicle has a body that is part of the main frame is misleading; the two components are distinct, with the frame providing the foundational support for the separate body.
