The air suspension is the self leveling suspension and is simply airbags that raise and lower the rear based on weight. I have it but it wouldn't really matter if I found a clean , low mileage truck. It was part of the adventure package but may have been added to any truck, I am not sure. The 03 did not come with the option of Navigation, rear cam , or parking sensors. All of that could be added of course by the owner, but none of that is important to me it is all about being unique. The H2 is kinda of a cross of luxury and ruggedness and each owner customizes to suit themselves. Other than my gas door I have added nothing to mine
