Hi ya, from what it says on a few sites and from experience you can do either, i am going to be getting one and intend getting a fitting kit so it mounts in the roof rails so i can take it off when not needed. My mate has one on his Transit and that is fitted to an old roof rack which he just takes off when not needed. At the end of the day its up to you how you mount it from what i understand of them
