East Anglia is Cambridge and, yes, I have been looking at Dom Fox's web site. He's not too far from me, so could pop up there one day to have a look around. It would be good to get inside a number of different vans and really start to get a grasp of their layouts etc.
In the meantime, I have been carrying on with my researches on line and looking for vans for sale - both here and abroad. It does appear there can be a significant saving to be had buying in Holland and I've already identified 2 or 3 vans that would fit my spec. However, I'm not rushing into any hasty purchases. I want to see a few vans first so I have a 'context' in which to make a decision...
