I've my Andersen WDH hitch for almost 3 years now, and I really like it. No need for a separate sway control unit. My towing setup is a 2017 Tacoma rated to tow over 6,000 lbs. Trailer is a 2009 17 foot Casita trailer. So I'm not in the same weight class as you are. But it works for me. The reason I bought it was for a problem of using a Reese WDH on my Casita trailer. The brackets that the bars chains have to be attached to where right where the Propane bottles where mounted on the front of the trailers frame. So instead of having the bottles relocated (expense) I found the Andersen WDH hitch. The brackets that the chains go into can be relocated by making the chains longer. My tongue weight is probably right around 450 to 500 lbs. I've still got the Reese WDH. makes a really nice boat anchor.
