Roof top Box

Could anyone out there reccomend the ideal roof box for a TD5.
My rails only cover the first sunroof and then "shallow out" where the roof rises.
I assume that this restricts the useable length of a box?

There seem to be several manufactures. Are they all the same with a different badge??

Anybody had any experience and can reccomend a make and model.

I await your responses.

Thanks

Hi, I use Thule gutter mounted bars and box even though I have roof rails which I have also left in situ, works out fine for me, regards Tots
