I agree that it would be cool to see air ride involved, and you're right how most of the new SUVs have air springs that soften things up. The only issue I have with this is it's dependent on how the damping rates are tweaked. For almost every mod so far that's used air springs, they almost always end up stiffer than standard suspension. The LR Defender, the ETK 1300, etc. all suffer from some seriously stiff ride quality with air springs. In my own experience, I almost always end up using the rally/offroad suspension option and it winds up riding closer to an air setup than the actual air setups in game. That being said, I trust OP will figure it out and knows what's best for his vehicle. Happy to still see developments on this!
