I ordered mine with them, our Avalanche has a similar box but only smaller. I call them saddle bags on the Avalanche, and when I was ordered the Rebel I called them the same, the sales guy looked at me sideways..... what are you talking about he asked??!! Anyways.....saddle bags sounds way cooler then " Ram Box"! Also I can still fix a small 400 Yamaha quad in side the Avalanche so no worries with a smaller quad. In short, I love them and I knew I needed to get them on the Rebel.
