When trailer sway becomes a problem, one of the most common pieces of advice RV owners hear is:
“You just need a bigger truck.”
At first glance, it makes sense. Heavier trucks feel more stable, sit lower under load, and have higher towing ratings. But here’s the truth many people don’t discover until after spending thousands of dollars:
👉 A bigger truck does not eliminate trailer sway.
In this article, we’ll explain why the “big truck solution” is a myth, what a heavier tow vehicle actually does (and doesn’t) fix, and what truly eliminates trailer sway at its source.
Heavier trucks often feel more confident when towing because they:
This can make sway feel less noticeable — especially in mild conditions.
But feeling sway less is not the same as eliminating sway.
No matter how large the truck is:
This geometry does not change when you upgrade trucks.
As long as the trailer can pivot behind the axle, sway is still possible — even with a one-ton or heavy-duty tow vehicle.
Trailer sway is caused by leverage and motion, not lack of horsepower or weight.
A trailer can sway behind:
The difference is how noticeable it feels.
In some cases, a bigger truck can actually make sway more dangerous because:
Hidden sway is still sway — and it can still cause damage or loss of control.
The myth persists because:
But towing ratings address:
They do not address lateral motion control.
Trying to overpower a trailer with a heavier truck is like:
The trailer still:
No amount of truck weight removes that leverage.
The only way to eliminate trailer sway is to remove the leverage that causes it.
That means controlling:
🎯 Where the trailer pivots
🎯 How lateral forces are transferred
When the pivot point is controlled, sway cannot begin — regardless of truck size.
Advanced trailer sway control systems like the ProPride 3P® Hitch use patented Pivot Point Projection™ technology to address sway at its source.
Instead of allowing free pivoting at the hitch ball:
This is why many owners tow safely at or near their vehicle’s rated capacity — without upgrading trucks.
This doesn’t mean truck size is irrelevant.
Bigger trucks are beneficial for:
But they are not a sway solution.
A properly sized truck paired with true pivot point control is safer and more effective than an oversized truck with inadequate sway control.
Many ProPride owners report:
When sway is eliminated, the need to “over-truck” the trailer disappears.
A bigger truck may feel more stable — but it doesn’t change the physics that cause trailer sway.
The Big Truck Myth persists because it feels reassuring, not because it works.
True stability comes from controlling the trailer, not overpowering it.
When the trailer’s pivot point is properly managed, sway cannot start — regardless of truck size.
That’s why real sway elimination isn’t about buying more truck — it’s about using better geometry.
