Trailer sway can be a result of crosswinds, drafts from passing semi-trucks or descending hills using incorrect braking technique, according to Mark Polk in his RV Tech Tips series on RVTravel.com. The front of trailers are aerodynamic to improve towing gas mileage, but the sides aren't.
How do I stop my trailer from swaying?
Checklist for Preventing Trailer Sway:
- Load your trailer with 60% of the cargo weight in the front half of the trailer box.
- Don't overload your tow vehicle.
- Don't exceed your trailer's maximum gross weight.
- Only load cargo on the inside of the trailer. ...
- Maintain a speed of 55 miles per hour or less.
What is it called when a trailer sways?
Trailer sway occurs when the side forces on the trailer cause the trailer to move side to side behind the tow vehicle. We call it “fishtailing.” Two factors are involved here: (1) the side forces on the travel trailer and (2) the location and type of pivot point that the trailer is linked to.
