My thoughts on the “ official” Roxor available options goes a bit further . My personal example is the hitch install. I went to my dealer , bought the ball mounted/pintle assembly. It was not long after I mounted the flat plate that I descovered the ball was 2”, fine for older trailers but not up to my standards when using the Rox to shuttle trailers around in the Yard , They all had 2 5/16” balls. I did make it work by eliminating the upper pintle section and some cutting away of ford edged material. ( I did ask the dealer to supply the correct assembly , he could not ). What I have will work,will know tomorrow. ...the point is , check carefully what Roxor offers , it may not be correct for your install.
