What should trucks transporting metal coils be equipped with aside from air brakes?

Trucks transporting metal coils should indeed be equipped with heavy-duty suspension systems. This is critical because metal coils are often very heavy and can be unstable during transport. A robust suspension system provides better stability and load distribution, which helps prevent the truck from bottoming out or losing control while on the road. Heavy-duty suspensions are designed to handle the added weight and dynamic forces that come from transporting heavy cargo, ensuring a safer and smoother ride.

Other options, while potentially beneficial for different types of transportation needs, do not directly address the primary concern of safely transporting heavy loads like metal coils. Backup cameras enhance visibility when reversing but do not impact the core stability needed for heavy cargo. Federal communication equipment is useful for maintaining contact and ensuring compliance with regulations, but it does not relate to the physical handling of the load. Enhanced climate control systems may provide comfort for the driver but do not influence the vehicle's ability to manage heavy, shifting weights like metal coils.
