The Road Glide Custom is identical to the Street Glide, with exception of course to the fairings. I would consider going to the RGC next time over my SG, I just can't get past the RG fairing look. Also, I like to trade fairly often, so I'm not really sure if selling the RGC would be as easy as selling a SG. Just my 2 cents.
