We are changing our tow car later in the year and have a VW Passat Alltrack on order for the middle of May or so.
As SWMBO is insistent on taking two grandchildren for a taste of caravanning life I ordered a roofbox in the shape of a Kamei Corvara 310 to give us a bit more room.
When it arrived,boy is it a whopper.
I didn't quite realise how long it actually was.
It is more like a coffin and will take SWMBO admirably if she gets gobby.
The moral is,if you are thinking of getting a roof box measure up carefully.
