ready for a better hitch...B&W or Anderson Ultimate

I have the Patriot on rails. Love it. I also have a MorRyde pin. I recently found out that you aren't supposed to use the Andersen with the MorRyde or other slider pins. I would've got the Anderson had it been out when I got my Patriot, but glad I went with the B&W as I ended up getting the MorRyde. Might be something to check into if you are serious on the Andersen. Like I said I read it on another RV brand forum so can't back it up totally.
