If I was thinking along the lines of a roof box, I would be looking at something that would fit between the bed ends when the FC is folded but before the Transit Cover went on. IE under the 4 frame poles but cross-wise across the FC.
There is loads of unused room under there and with the Transit Cover then tied down, no one would know you even had a roof box there.
That's where I stick my bedding in that part lobey.
Thanks Kelper, but I've got my eye on some on e bay. Either a buy it now price or offer £40. But thank you for the offer :)
