That appears to be a van.
You are right. It’s a VW Crafter, and it’s rather big. In fact, since we’re not counting subsidiaries such as MAN and Scania, it’s actually the biggest vehicle to wear a VW badge. Get it in its biggest guise, with the longest wheelbase and you have a vehicle the best part of a metre longer than a Phantom Extended Wheelbase with the ability to cart 15,000 litres of stock. If you could fill it with water you could call it a swimming pool.
