When transporting a load on the roof, what should be done with unused ski boxes?

When transporting a load on the roof of a vehicle, it is important to consider the impact of any unused ski boxes on the overall fuel efficiency and vehicle dynamics. Removing unused ski boxes is recommended because they add unnecessary weight and drag to the vehicle. The presence of these boxes can increase air resistance, leading to higher fuel consumption while driving. This is especially pertinent during highway speeds, where drag has a more pronounced effect on fuel efficiency.

In addition to fuel consumption, retaining unused ski boxes can alter the vehicle's center of gravity and handling characteristics, potentially compromising safety.

By ensuring that the roof is free of any unused or unnecessary items, drivers can optimize their vehicle's performance and ensure a more economical and safer journey.
