A stabilizer is specifically designed to improve vehicle handling when towing a caravan or trailer. It works by reducing sway and lateral movement of the trailer, providing a more stable towing experience. This is particularly important because the added weight and dynamics of a trailer can affect the handling characteristics of the towing vehicle, making it prone to swaying, especially in windy conditions or during sudden lane changes.

The stabilizer helps to keep the trailer aligned with the towing vehicle, enhancing overall control and safety. By minimizing the effect of side winds and creating a more balanced towing setup, drivers can maintain better control over their vehicle, which is crucial for safe maneuvering on the road.

While other devices mentioned can contribute to vehicle safety and performance, they do not specifically target the issue of sway and lateral stability in the same way that a stabilizer does. An electric brake controller is used to manage the braking system of the trailer, an anti-roll bar aids in reducing body roll during cornering, and belts and chains are primarily safety features to secure the trailer to the towing vehicle, rather than improving handling during towing.
