body-on-frame

Truck's structural design

Body-on-frame is a vehicle construction method where the body mounts on a separate structural frame, like a house on a foundation.

This older design predominates in trucks and SUVs because the rigid frame handles heavy loads and towing stress.

The alternative, unibody construction, integrates body and frame into one unit—lighter and more fuel-efficient, but less rugged.
