Tow ball height

[MurrayR]

Looking to purchase a caravan. The caravan coupling height is 440 mm but the VW Ball height is about 350 mm. What do you do to correct the difference in height?

You might find a solution here.
Basic Airbag system where you use an external compressor to pump to required height and simply deflate down when unloaded.

I sourced an Audi A4 detachable coupling that was higher and only slightly further away from bumper.
