Good luck with the trip! Dundee is a Lomg way to go and collect a van, Baz and I did almost the same trip in 2009 to collect Peggy, but she came back on a trailer (which is what caused all the aggro on the way back).
We'd love to see you at the meet in ivinghoe. It's about 5 miles from J11 on the M1, so not far from you, and you would have a good opportunity to meet some of the people on here, and show off your new van before Santa gets here.
Cheers
Andy
