What is a potential consequence of additional weight on a hitch affecting rear suspension?

Additional weight on a hitch can lead to increased wear on the vehicle due to several factors. When a trailer is loaded with more weight than the vehicle is designed to handle, it alters the load distribution. This added weight places an extra burden on the rear suspension system of the vehicle, which is responsible for supporting the weight of the rear of the vehicle and maintaining stability.

The rear suspension experiences heightened stress when accommodating this extra weight, which can lead to accelerated wear on components such as springs, shocks, and other associated parts. Over time, this increased strain can result in mechanical failure, decreased ride quality, and potentially dangerous driving conditions, as the vehicle may not handle as well under these circumstances.

In contrast, improved fuel performance, better stability of the trailer, and no impact at all would not accurately describe the consequences of adding excessive weight. Improper load management can have significant negative effects on a vehicle's performance and longevity.
