The receiver type hitch is what I use and I use a Rivco you can remove the ball and not see any hitch, I would recommend a swivel hitch I have see bikes pulled over from taking the curves to aggressively and wind can blow it over also if the trailer goes the bike will also go over.

I have a Kuryaken hitch and a plug and play wiring harness. It is simple and neat. I live and ride the mountains of east Tennessee and western North Carolina. Even riding the twisting roads around here I've encountered no need for a swivel hitch. The reciever hitch does give a slightly cleaner look, but I like using my ball as a bumper when I back into my garage I can just back up until it touches the wall and I get all the way back with never touching any other part of the bike against the wall.
I have a receiver hitch on my Roadking. When it is removed it is invisible as the receiver is vertical up inside bottom of fender. I also have the wiring converter etc. I am taking it all off here in about a week or so as I sold my trailer last year. I also have a cool little platform that goes into the hitch so you can carry a cooler (with or without your trailer) or some golf clubs or whatever. My trailer had a swivel hitch and it was very nice . Don't want to hit you with a sales pitch but this stuff I have will be for sale once its off and I see you are right next door in B.C. If you are interested in my parts private msg me and we can talk.

Update; Sorry. I don't think that will fit your bike even if you wanted it? I forgot that they changed the fender etc later on. Some of us old guys are stuck in old days. LOL
