Air Lift 1000 Question
 

Has anyone ever put an Air Lift 1000 on their X5? Does anyone know the coil dimensions necessary to figure out which one to order? I'm looking at this as an alternative to getting the self-leveling suspension since I've found a diesel with adaptive drive, comfort seats, and steering wheel heater (finding 1 with all 3 is like finding the Triforce). This seems to be a reasonable workaround for the lack of self-leveling rear since it is my intention to get a travel trailer.
