Which factor is NOT important for weight distribution in a heavy trailer?

In the context of weight distribution for a heavy trailer, ensuring that the placement of items contributes positively to the stability and safety of the load is crucial. Keeping lighter items towards the top of the trailer is not a recommended practice because it can lead to a higher center of gravity. A higher center of gravity increases the risk of tipping, especially during sharp turns or uneven road conditions.

In contrast, placing heavier cargo towards the front helps stabilize the trailer, as it guides the center of gravity lower and more towards the axles, improving handling. Even weight distribution across the axles is essential for ensuring that the trailer maintains a balanced ride and prevents excessive wear on tires and suspension components. Securing heavy items in place is crucial to prevent shifting during transit, which can disrupt weight distribution and compromise safety. Thus, while all these factors play a role in weight distribution, keeping lighter items at the top is not beneficial and can be detrimental to safe handling.
