And if its more complicated than that where would you suggest i go to get a quote/get it installed. A local diesel mechanic? Or like a RV/bus service center?
"Air ride" suspensions completely eliminate springs but yes, they are similar to the assist kits you are referring to. Factory installed setups are *MUCH* more robust and the weight of the vehicle is entirely supported by the "air bags" and associated parts.
This is one modification best left to professionals because you'll need some big tools and know how to do the job safely and properly and many insurance companies/policies will void any coverage if it's not done "professionally" (by some company with their own insurance, that can be sued if it causes a crash), for obvious reasons. On a full size bus, it will consist basically of cannibalizing a suspension from a donor vehicle and refitting it under yours. This would be an excellent time for an axle/gear ratio swap if one is planned.
