We had a similar van during Eurocade, but I think this one has a longer tail behind the rear wheel.
I don't remember exactly but we had to run 2 times with all my cabs back, and of course on 1 run we had the SW cockpit.
I think we had 6 or 7 uprights during the first run. The really high cabinets you need to put in "front down" first and not the other way around as you will not be able to get them vertical again if you move them in "laying back" on a hand truck.
For this, I strongly advice you to get a van like this:

...and the tail-gate lift is simply something you won't want to be without if you have to move a large number of cabs.
....however......there is a con to the tail-lift: it eats up a lot of the weight that you are allowed to transport...
