Hello: I originally installed a "Wompus" rack. $225 if I remeber correctly. I have since replaced the smaller orignal trunk with a Harley Tour pack. I chose to keep the Wompus rack and I mounted the Tour Pack to it. Nothing is cheap. I got by with about $750 total. I like it more every day I have it. Others have replaced the RSTD side rails with RSV rails and a RSV rack, $375?? and then installed a Tour pack to the RSV rack. TDbiker, LoneEagle, myself and numberous others have went this route. I have the best of both worlds. Dependable V-4 Yamaha and a large side open tour pack. Encreased lighting. Works for me.
