An apparatus comprising:

• a vehicle frame including:
• a first inner elbow and a first outer elbow on a first side of the vehicle frame;
• and
• a second inner elbow and a second outer elbow on a second side of the vehicle frame, the second side opposite the first side;
• a first backup rail coupled to the first side of the vehicle frame and extending across the first inner elbow and the first outer elbow;
• a second backup rail coupled to the second side of the vehicle frame and extending across the second inner elbow and the second outer elbow;
• a first cross-member coupled to the first backup rail at the first inner elbow and to the second side of the vehicle frame;
• and
• a second cross-member coupled to the second backup rail at the second inner elbow and to the first side of the vehicle frame.

An apparatus comprising:

• a vehicle frame including:
• a first rail and a first rocker on a first side of the vehicle frame;
• and
• a second rail and a second rocker on a second side of the vehicle frame, the second side opposite the first side;
• a backup rail coupled to the first side of the vehicle frame and extending between the first rail and the first rocker, the backup rail to transfer a first portion of a longitudinal load on the first rail from the first rail to the first rocker;
• and
• a cross-member coupled to the second side of the vehicle frame and to the backup rail at a bend of the first rail, the cross-member to transfer a second portion of the longitudinal load from the first rail to the second side of the vehicle frame.
