I have a GS 2009 SE5
I have some 8000 miles with my trailer behind mine you barely notice its there
make sure to load your trailer evenly not to overload the hitch
I use the ebay hitch
here is one I just looked for and a screaming deal I paid 200 for mine

made my own wiring connections using tricled items at the bottom of the page you will need 2 of the 2 wire for turn signals and one 3 wire for brakes and running lights super easy

I used these for my bike to trailer connections fit nicely in provided bracket on the hitch

do it your self and know your bike
[I have a 2012 RS-s with over 40000 miler pulled the trailer to Mo spyderfest twice and twice to Durango No problems. be sure to get your wire connectors from TricLed :yes::yes: jtpollock ]
