I got an eaz hitch with my used trailer....the tow vehicle was too small, so I got a 1/2 ton GMC rated to tow 9400. Much better.....but, we traded our used TT on a new TT (4k lbs)
The eaz towed OK, but, I wanted better. I bought a Hensley Cub (used), we have been over 1k miles with the rig -GMC, Hensley Hitch, 4k lb TT and...I am thrilled, it tows great, it feels safe, and it does what it's supposed to do..No Sway
The point is, I evolved through the options until I found a comfortable combination. You will eventually get there too, just keep an inquisitive & open mind.
