I have just converted a Long wheel base high top transit into a camper - with wife kids and dog in their I still need to store my boards on teh outside. The main option seems to be roof bars and then some sort ladder to get to them. I have seen some vans with boards attached to the side of the roof (also seen ladders carried this way) but I don;t seem to be able to find anything about this. Does anyone know what this is called or where I can find them?

Thanks
