I cannot address the suitability of your VW for towing, but as to the tow bar height issue, my Blue Ox tow bar manual states:
"CAUTION:It is important that the attachment points at the center of the attachment tabs and the center of the coach's hitch receiver should be of equal distance. If a deviation must occur, then it is recommended that the hitch receiver be no more than 3” above or below the attachment tabs of the baseplate.
I had to add a drop hitch receiver (https://genyhitch.com/
) to my Hurricane 35M because there was a 6" difference between the 2 measurements.
