Tow set up is simply not hitch and go. Is your vehicle level when hitched? If not, your set up is not correct. Tongue up can cause sway - you can fiddle with your set up, change balls, etc. but hitched needs to be level. When I tow, I drop my front tire pressure a tad and pop up the back just a tad.
Have you weighed your vehicle? Many hitch and go, but you should get yourself, your vehicle and your trailer to a weigh station. I have one by my house that I can peek through the windows when it is closed to see the scale numbers. Have your vehicle loaded as you would to travel; belongings, tank filled, passengers if you can. Weigh your vehicle unhitched but loaded; total, front axle, rear axle. Then weigh your trailer: tongue, total trailer weight. Then hitch up; weigh your entire combo, then just your trailer axles, just your front axle, just your rear. Make sure your numbers are all in line with your actual tow capacity. You need to make sure you are below not only your tow ratings, but your GCWR, your payload ratings and your hitch capacity.
And you really do NOT want to load up and be at your limits. You can hitch a trailer to almost anything and drag it down the road, maybe not safely but you can; you have to be able to stop that load as well.
It takes patience and fiddling to get the right combo but once you dial it all in, you should be good to go so long as you do not change anything - like add a passenger, change around your load, etc. and if you do, you'll want to repeat the whole process. There used to be a worksheet years ago that you could get online but it's really not necessary so long as you weigh every step of the combo and ensure you are not over capacity. If you have your capacities right, and your distribution of weight done properly, and your vehicle level - you shouldn't have sway. The Husky will do a great job, but it can't do anything if your set up is wrong.
