My suggestion is more expensive... Not what you are asking but I owned one and I swear by it. .
The Hensley Hitch... . If you are not familiar with it. . go to
www.hensleymfg.com ... You can get a free video to check it out.
This is a WD hitch and Anti-sway all in one. Also all of the hitch stays on the trailer as you see in the pic

here is the only thing you take off when unhooking. It is the towbar and you get the one you need to make the trailer level when hooked to the hensley. Up to 8" rise or lower.

Here is how the hensley turns. The lower black unit hooks to the towbar which hooks to the receiver on your truck. When you are in a straight line, there is no pivot so it has the same feelings of a 5th wheel. That is the antisway. when you do a turn, the mechanics of the unit then make an angle for turns. Follows closer and does easier backups.

here is a drawing of the hitch so you can see the whole thing

Heres a side view of the unit hooked up. . had this on my 28' Desert fox Toyhauler

My Ravings? WONDERFULL!!! When I first drove this in high crosswinds, and had almost no sway, no more than like 5th wheels, I was impressed. I drive truck for a living and I have see alot of TT that rolled because of Crosswind sway..... Bet they had things like the 4 link and so and so... . didn't help bacause it still has a pivot point when straight...
Cost? About $3,000 You might be able to get a demo unit for less if there are some available.
hope this helps you decide what to get. If the Dual cam is better then get it but I seriously suggest the Hensley.
