Abstract: A trailer having a tongue that defines a longitudinal axis and includes a coupler portion. The coupler portion of the tongue can pivot relative to the longitudinal axis, thereby forming an angle between the coupler portion and the longitudinal axis. In a preferred embodiment, the tongue includes a breakaway coupler assembly. The breakaway coupler assembly includes the coupler portion having a distal end adapted to engage a towing vehicle, and a flex-joint pivotally engaged with the coupler portion. This allows the coupler portion to pivot relative to said flex-joint when a predetermined force is placed on the flex-joint, such as in a jack-knife situation.

Abstract: A truck chassis frame is constructed to provide storage space for a loading ramp between the longitudinal frame members. A transverse frame member positioned beneath the longitudinal frame members is connected to the longitudinal frame members by brackets secured to end regions of the transverse member and to the outer face of the C-shaped longitudinal members. The space above the transverse member including the open regions of said longitudinal members is open to provide the storage space.
