Hayes Sway Master Elec Sway Control. Does it really Work?

Thanks for the info. I already installed it on my A frame of my 2017 Jayco
28 ft TT. 6,000 pounds dry weight. TV is 2008 GMC Yukon Denali 6.2 Liter with K&N Cold Air Intake, Flowmaster Cat Back, upgraded Trans Cooler, NAPA Ultra Premium slotted Rotors and Premium Pads, Bully Dog GT tuner, Equalizer WDH, Quest Electronic Brake control. I am going on a 100 mile road trip to a campground for memorial day weekend. This will be the first true test. I will keep you posted and let you know what I think.
