Actually big vans and even 3 ton box trucks are easier to park than cars because they have good mirrors and you can gauge your distance between the box corner and an object accurately. As long as you understand how the front of a vehicle moves when you steer, reversing vans and small trucks is easy. I used to have to reverse a 3 tonner into a warehouse then make an immediate turn down the side of the building and I can understand how artic drivers can reverse with such accuracy.
Sorry to burst your bubble ;(
