Trailer length is one of the most misunderstood factors in towing stability.
Many RV owners experience trailer sway for the first time and immediately downplay it.
For decades, RV owners have been told that trailer sway is something you simply “manage.”
Most RV owners assume heavier trailers are automatically harder—or safer—to tow. But when engineers analyze towing stability, they often discover something surprising:
Most RV owners focus on weight, speed, or vehicle size when thinking about towing safety. But the real foundation of stability lies deeper—in geometry.
Trailer sway doesn’t usually start as a violent, uncontrollable motion. It begins small—almost unnoticeable. But then something happens: the movement grows, swings wider, and becomes harder to control.
If you’re researching trailer hitches, you’ve likely come across three common terms:
Trailer sway rarely starts as a dramatic, out-of-control event. In most cases, it begins quietly—so subtly that many drivers don’t even notice until it becomes dangerous.
