Side roll as you enter a curb cut with a dip or rise is always a challenge for a suspension and air suspensions seem harder to control than spring in that regard.
Generally you shouldn't just adjust the suspension higher/firmer because it changes the drive shaft angle at the rear, basically putting the drive shaft out of alignment. Manual systems that let you override are to be avoided because a moments forgetful ness in resetting to auto-air management can lead to serious and expensive damage.
Motorhome air systems are already self-leveling and auto-adjusting, but they don't react quickly enough for a turn into a dip or rise. Something like the
Comfort Ride air control valves might help your rig get thru those situations without any negative effects elsewhere.
