I bought a hitch with the receiver, so when the hitch is out you can't even see it, bought a little used trailer back when I had the EGU and had out repainted to match the RGU. I love it but the wife loves it even more, she gets to take her shoes. Went with Kuryakyn wiring harness, it draws power from the main circuit instead of the lights, hooked it to the Acc switch plug under the seat so when I'm not using the trailer I can turn it off. Can't remember who makes the hitch but I got it off Ebay, bout $175 for the hitch.
