HMS Beagle,
I'm fully aware of what your air ride system is and what airbags are. I had been doing pickup, van, and SUV component design and engineering for nearly 40 years before I sold my engineering company and finally retired. The main thing in the air ride systems is the ability of using the contained/captured compressed and compressible air pressure to greatly lessen the transferred shocks and jolts created by road imperfections and unevenness in vehicle suspensions to the occupant's bodies while giving all the needed suspension support required. All done with PSI inflation which is always available rain or shine, -30 F or 130 F virtually anywhere on the planet Earth. Air is free! Nothing even compares to compressed air's functional ability in actual performance vehicle ride quality. Nearly zero recoil action when done right and can almost negate the need for shocks being needed.
Air-Lift and other like inflatable stand alone airbags are an important fully adjustable assist to OEM conventional suspension systems. They can be inflated to become a low assist factor all the way to being the major support factor to the point where the OEM spring support could actually be removed and another alignment axle tie in management system installed. Basically, none of this is really new and it was first developed and used nearly 90 years ago. Cantilever arm type airbag suspension is ages old and can be excellent when done right. Just requires a lot more bracketry and expense to alter to and adds a lot more weight unless the OEM springs are totally removed. Lots of trade offs! Yes, I do like your system and setup and should have nice results.
