:hijacked: Ohh seven seats?You got any pics?
I also have air suspension so the only option I could find was a swing away carrier supplied by pivlock - Bullivant Engineering :- Makes of Pivlock
Found it quite easy to fit and has now been on the car for about 4 years with no trouble. I also think it looks pretty smart.
Tried to put photo of Pivlock Swing Away wheel carrier here = hope it works.
