I have a 2,000lb boat and tow with my 2000 Grand Marquis, which has a 3.55 rear and air suspension.
When I remove my boat trailer hitch, I have to wait about 30 seconds for the car to lower with the engine running. It takes several minutes if the key is off. This is a slight pain, because my trailer jack doesn't lift high enough, unitl the car lowers. But the air suspension sure works well for me.
By the way, the air suspension module is tied into the steering sensor. It will not make changes when you are making turns.
