Save yourself $1000. I got tired of waiting for the Indian tour pak and desperately needed something for my Sturgis ride last month. So, I bought a 2014 Harley tour pak, got a fantastic luggage rack/bracket specially made for the Harley/Indian conversion from Thunder Manufacturing in Phoenix, put it on my Chieftain and it worked and looks great!
I saw the Roadmaster Tour Pak at Sturgis and, while it looked nice, it had a LOT LESS storage than my Harley Tour Pak does.....you can fit 2 three quarter helmets and that's it....
Granted, I'm going to have to add lights and electricity, but I'll still be well below the $2500 Polaris is charging....
