Center of Mass, Tongue Weight & Stability
The Physics Most RV Owners Miss

Most RV owners use the word sway to describe trailer instability.
RV travel isn’t just about destinations—it’s about who’s in the vehicle with you.
Crosswinds are the ultimate real-world test of any towing setup.
Most conversations about towing focus on hardware—axles, tongue weight, suspension, ratings.
Upgrading your RV is exciting. A longer floorplan. Bigger tanks. More storage. Maybe even a move from a half-ton tow vehicle to a three-quarter-ton truck.
When RV owners evaluate a hitch, the first question is usually:
“How much does it cost?”
Most RV owners think about braking in terms of weight: heavier rigs need more distance to stop. What often gets overlooked is how trailer sway dramatically increases braking distance and slows reaction time, even when your brakes are functioning perfectly.
Most towing equipment loses value the moment it’s installed. A few seasons later, it’s outdated, worn, or replaced by something “better.” But the ProPride 3P® Hitch is a rare exception. Even years after purchase, ProPride hitches consistently command strong prices on the secondary market—and often sell quickly.
Most RV owners think of trailer sway as a handling problem—something that feels uncomfortable or scary in the moment. What’s far less understood is that trailer sway is also a mechanical stress problem that quietly shortens the life of your trailer.
