Not exactly, I did ask and was advised that 3.2m clearance would be fine (I have 3.3m opening in my shed). I am getting 17" wheels which obviously increase height more than 16" which are the more common wheel size. I looked at the same model van in the factory which was about 95% assembled, 3.1m does appear to be the typical Kedron height.
Currently they have quite a few vans assembled (18) and at the factory ready for the Brisbane Caravan Show so it should be possible to contact them and get them to give you a height for a particular model van. Don't forget to ask what size wheels they have fitted, it is only a small height difference, but could be important if tolerances are close.

PS I should add I got swing doors made for my shed by a Colourbond fence supplier in Queanbeyan, they are really garden gates max height 3.1m, so I have yet to add 0.2m of Colourbond on top of gates (doors), they cost $1500 to get made, but are real solid and well made.
