Sound Guy, you are correct. Don't expend much more of your energy.
I have an Equal-i-zer brand and am very happy with it. I have actually had two, a smaller one on my first trailer and now the one I am using. Never had a problem with sway, never had a problem hooking or unhooking and always feel at ease towing with it. When I was first looking I didn't like the whole idea of snapping those chains into place and I really didn't like the issue they had with friction sway bars. Back then, you couldn't back up with them and you had to tighten them down. I never could figure out how tight to tighten them and if I needed one or two.
Today there are many hitches with built in sway control. Reese dual cam as someone has mentioned is a good example of one. If you have an Equal-i-zer hitch, use it and see how it works for you. Progressive has a website where you can get all the support you need to set it up.
