Get either a Reese/ Drawtight dual cam hitch or Equalizer brand. Would not tow with anything else. Also Prodogy brake control unless you have factory unit.
Did not mention Hensley as they are overkill.
Ps nice Rockwood model you are getting. We would have bought same model if I had not stumbled upon 5th wheel deal of the year.
