Looking at the link. I reckon you would have problems with the windows closing. It could even damage the seals.you could try something like this, if its not to heavy a load.
but do so at your own risk
I put a hitch on the back of my car so I can use the small cargo backets & a bike rack.ye i know it wont look cool, but is there a roof rack for the Eos???? as i have to pick up a Kayak (2.6m),
or does anyone have a cunning other idea?
I added a hitch- use with both a cargo basket and bike bike.It is not possible to fit a roof rack to the Eos due to the load limitations on the roof. Came up with a similar problem when I wanted to transport my bikes and ended up buying a campervan with a cycle rack
