Yes it has air suspension.
You can lower the whole coach, or have it at ride height. You can not lower and drive.
You can not lower just the front, as it's set up from the factory.
You can, with spending around $11,000), have HWH Active Air installed.
You'll have to call HWH to find out if their regular air leveling ($5000) can be added to the 2016 Freightliner chassis. It could not on the 2015.
I had regular air leveling added to our 2013 coach and love having full control of my air suspension.
Active Air takes it ten steps further.
