To bring this thread back on topic...
With height restricted entrances / bars etc. you need to be careful, the van may fit under the bar comfortably as you first drive in, but if the ground rises too quickly on the other side you will catch the middle - if you follow.
I am speaking from experience...
There is a car park in Lancaster behind The Sugar House student night club (which I spent way too much time in as a youth, and met my wife there!!) it has a bar which a standard height Bongo (i.e. not lowered, or big tyres) will fit comfortably under until a quarter of the way under, then the front tyres hit the rising ground and you scrape your AFT!!
Have backed off other height restricted entrances following this experience.
