There is no such thing as overkill as regards best hitch type. Especially when fulltimng. Settting up a two vehicle combination on a set of certified scales to get formula values correct is worth the small amount of time & trouble.
The VPP hitches -- Pro Pride first, and Hensley second, -- are the standard for WD hitches with integrated antisway. Others resist sway, these "eliminate" it.
Second tier -- and a very long ways down -- would be the REESE Dual Cam, and then the Equalizer.
After that would be the standard friction bar type. A bad choice.
An Andersen "might" work if the TT had a tongue weight of a few hundred pounds. It is otherwise not suitable. Very few have been able to make it work according to any formula of correct WD hitch set-up. "Weight distribution" is a requirement and "anti-sway" is optional, so don't mistake one for the other in re opinions.
