I seem to remember that a caravan magazine tested the Dispatch for its towing manners. After the initial handling tests, the driver refused to do the emergency swerve/brake test as he was already convinced it was too dangerous.
I hire all sorts of vans for work and I wouldn't go for anything too small. If you look at the floor plan of a medium sized van they are not much bigger than a large estate car, they are just taller. I don't rate the VW - a bit under powered IMO and it has a horrid coffee cup holder! The renault has long gears so it is good for long runs with light loads and it can also go on the M6 Toll as a car (but don't tell anyone). I had bad experiences with Toyota (as well as coffee cup issues) if I was ever reckless enough to get the driving wheels off the tarmac. The Merc Vito is a tidy size and very quick but there is always the terrifying prospect of accidentally applying the (foot operated) handbrake when going for the clutch on the motorway. My favourite is the Transit. The cab seems to be made for a real person who needs places to put stuff, the engine is good and grunty (same as new defenders) but with six gears it can (allegedly) cruise at a ton. The downside is going to be price to buy, price to fix ("Ford" rhymes with "fraud"), and the cost of all that diesel.
