just leave it at it's ride height ..will advise when pulling out from a trailer ,once disconnected from the pin ,lower the suspension till your off the trailer .otherwise the back end will shoot up like a dragster ,which won't do shock and air bags any good ,and can also in some circumstances smash your rear lights and wheel arches ...as they make contact with the trailer...is common to all air suspended trucks
