Why is it important to distribute heavy freight evenly across both the left and right sides of a commercial truck bed?

1. Uneven lateral loading causes the truck to lean, severely compromises cornering stability, and causes early rollovers on curves
2. Uneven loading is corrected automatically by the vehicle's suspension
3. Lateral balance matters only on vehicles fitted with air suspension
4. Side-to-side balance affects tyre wear but not vehicle stability
