You won't get a consensus here.
Fundamentally, there are two types of weight distributing, anti-sway hitches. The Hensley and the ProPride are VPP hitches that, by design, eliminate the possibility of sway, according to their manufacturers and a great many users. They are heavy, however and very expensive (at least to me).
Then there are systems made by Reese, Anderson (a product people love or hate, not much opinion in between) and Blue Ox. I use a simple Reese straight line hitch with friction bars and it works for me on my 1986 31'
Sovereign.
The Blue Ox seems to have a lot of happy, satisfied users and costs about a third what the Hensley and Pro Pride cost. If I was buying today, that is how I would probably go.
Shortly, someone will post their favorite, condemning all others and that will likely continue for awhile until you have heard from fans of all the major brands. Then you will hear from the 3/4 ton diesel or larger crowd for awhile, with a few posts from people towing with other, smaller vehicles, all of whom are convinced that their choice is the ONLY core t one.
So, basically, Google up the major brands mentioned. Maybe even visit the nearest campground and ask folks with similar sized trailers what they use and how they like it. Then you pays your money and takes your chances...
