I have a 2012 RT and recently added a trailer hitch on it. It's an "After market" one but it's working pretty darn good. My problem is that to install it, one step is to loosen the rear brake set up. There's a "pin" for lack of a better word. Or bolt actually. It keeps the brake mechanism from moving around. I was checking it over after a short ride and noticed the "bolt" was working it's way loose. At the end that goes from housing to the frame there is a clip that fits into a indentation in the bolt/shaft. It looks like it should have a "spacer" to keep the bolt in the proper place so it won't loosen. Anybody have this type of set up? On another subject is there a Spyder RT "Base Model and a step up being the "RT Limited?" Just curious!
