I have used both the Equalizer brand and for the past 12 years a Husky Center Line. Edited the link, I used the TS one, that had sway control built in, not the other cheaper one.

I towed a twin axle 30 foot toy hauler with my F350 with the Husky and it worked really well. So much so, I have three friends that have purchased the same hitches and they have all had great luck with it also. I have towed my camper from CO to FL and all over the west, including a lot in windy Wyoming.
Like a dumbass I bent the bars very early on. I called Husky and they replaced them for free. So great customer service as well.
Too bad you are not closer to CO, I would give you both my older equalizer and the Husky to try out and keep if you wanted for free as I moved to a Super C and sold my toy hauler.
Feel free to PM with any questions.
