In reply to birdie num num:
Only saw this post tonight so may be a bit late.
I have a Fiamma three bike carrier for a VW T5 which I don't need any more. It has been in my garage for a couple of years unused.
I am not sure whether there is much difference between the two models of van but if not and you are willing to spend a little cash it's an alternative to a tow bar carrier.
May be an issue around collection as I live in the north east.
