We have transporters at work (mines a 2011) 140, stick a trailer on the back and get on some wet grass and you will be stuck. The van on its own (2550kg) gets stuck too easily. All the lads that had the older version have all said they drove better and felt more refined than the newer ones.
The newer ones are great on fuel tho. They do do a 4motion one but no idea what they are like.
