some info I've come across regarding operation of the air suspension:
The RAM air suspension system provides full time load leveling capability along with the benefit of being able to adjust the vehicle height by the push of a button.
- Automatic height changes occur based on the vehicle speed and the current vehicle height. Indicator lamps and EVIC messages will operate the same for automatic changes and user requested changes.
- Normal Ride Height (NRH) – This is the standard position of the suspension and is meant for normal driving.
- Off-Road 1 (OR1) (Raises the vehicle approximately 1 inch (26mm)) – This position should be the primary position for all off-road driving until Off-Road 2 is needed. If the vehicle exceeds 50 MPH the vehicle will automatically lower to NRH.
- Off-Road 2 (OR2) (Rises the vehicle approximately 2 inches(51 mm)) – This position is intended for off-roading use only where maximum ground clearance is required. If the vehicle speed exceeds 25 MPH, the vehicle will be lowered to OR1.
- Aero mode (Lowers the vehicle .6 in(15mm))-1500 models only – This position provides improved aerodynamics by lowering the vehicle The vehicle goes into Aero mode when the vehicle speed remains between 62 MPH and 66 MPH for greater than 20 secs, or if the vehicle exceeds 66 MPH.
- Entry/Exit mode (Lowers the vehicle approximately 2 in (51 mm)) – This position lowers the vehicle for easier passenger entry and exit as well as lowering the rear of the vehicle for easier loading and unloading of cargo. To enter Entry/Exit mode, press the down button once from the NHR while the vehicle speed is
So I don't think issues will arise from the mechanical components, airbags have been around long enough that I'm sure mechanically they are sound. What I do worry about, and likely enough to cause me to forego the air suspension is the software running the show. Chrysler has a spotty record with software as of late regardless, and clicking around ramforumz I came across a few guys who are seeing their RAMs completely misbehaving. One guy says when he tries to lower the truck will bounce right back up after a couple seconds. Plus if you do some digging around into the Jeep Quadra Lift suspension which is basically the same as the RAM suspension you will find it is rife with issues...
Another guys truck is stuck in offroad 2 and refuses to come back down!
