Reese Dual Sway Control Bars work great for towing heavy trailers. See below
for manufacturer details.
This patented product is Reese Products main technique for controlling trailer
sway. Unlike the friction sway control, this approach works to control sway
from the start rather than just resisting sway once it's begun and it works
only when needed. When towing in a straight line, the cams on either side of
the trailer A-frame are locked in position. This essentially creates a "rigid"
connection between tow vehicle and trailer and minimizes the effects of induced
sway caused by high cross-winds or passing vehicles.
Usually, the cams ride in a detent locked-in position, even on fairly sharp
curves. However, when cornering maneuvers are required, the cams automatically
slide out of their detent to permit full radius turns. Yet when the maneuver is
short and abrupt, like that encountered in the event of a sudden swerve or a
wheel dropping off the road, the cams seek a straight-line towing angle that
helps the tow vehicle retain control.
The advantage of the dual cam system is its ability to forestall sway in
addition to sway resistance. It works to hold down the start of swaying
activity while at the same time allowing free and easy vehicle and trailer
interaction. Another advantage of the dual cam system is that it's installed on
the trailer and therefore doesn't require adjustment every time the towing
vehicle and trailer are hooked up, unless hitch weight or tow vehicle loading
