How does raising the Center of Gravity (Centro de Gravedad) of a cargo load affect the handling and stability of a heavy truck?

1. It improves aerodynamic efficiency and reduces stopping distances
2. It drastically increases vehicle body roll, increases rollover propensity during cornering or evasive maneuvers, and reduces lateral stability
3. It eliminates the need for tie-down lashing straps
4. It lowers the temperature of the braking system
