Do NOT get the air suspension if you live in a cold climate. It fails. It is a serious safety issue as any or all sides of the truck can bottom out while you are driving. The front end bottomed out while driving on the highway at night, so the headlights only shine 2-3 feet in front. Truck does not handle as it should when the suspension is off. It is not a closed system, so moisture gets in. Dodge dealership currently has no fix for this and there has been no recall as of 2017.
