2012 Ram 2500 CTD towing a 33.5 ft. Outdoors RV Blackstone. Started with the Equal-i-zer four point friction hitch that was set up correctly and after a white knuckle experience, researched and purchased a ProPride 3P and after towing with it for two seasons there is no way I would go back to a sway control WD hitch vs the sway elimination design of the ProPride or Hensley. The precious cargo on board is worth every extra $ IMHO!
And, I agree with the others regarding towing a trailer that big with a half ton, but if that is what you are going to do, be careful and give some serious thought to a ProPride 3P or a Hensley Arrow. BTW, the PP 3P is the next generation HA.
