Spot on Bushman, the local dealers tow alot of there vans back to there yards. They use a variety of tow vehicles from small trucks a 100 series Cruiser and a single cab tray ute. Plus a few more I can't think of right now.
I think Page Bros have a Troopy and a Patrol, its only a 15 or so minute run though.
Edit: I was following a new Van getting delivered along Eastlink around 10 months ago and one of the safety chains was bouncing along the road :tape2: it wouldn't look to pretty when he got where he was going.
