WDH=weight distributing hitch.
These are a great hitch and I got my Husky wdh for around $250 on Amazon for my 2012 Ram 1500 and 2013 FR Surveyor 220. It cured the sag when properly hooked up and it tows so much better now; be sure if you get one or have one put on that they match the tongue hitch weight of the trailer to the hitch.
Given a lot more pesos I would get the ProPride 1400 setup but it's really pricey but I hear well worth it.
I don't use a friction sway control with my WDH and the trailer still tracks straight and true even in wind or being passed by semi's.
