Adding air suspension to the living quarters
 

Has anyone added air bags to the living quarters (box) on a toterhome or do you just rely on the air ride system on the tractor? I am building a toterhome on a 2008 freightliner m2 and plan to use a 15 foot dry van body. I would like to add additional air ride for the passengers in the living area. Is this foolish? Is there a kit that one can buy or is it a fabrication job? Is it necessary to even go about this part or should it just be mounted to the frame and quit over thinking it?

Mount to frame as the weight is gonna be to high unless you add multiple bags. It also going to be hard to keep it centered etc just by shear size of the box (dont think a lateral bar will do the job). Most toters (correct me if im wrong) are solid mounted including the cab and just rely on air suspension seats.
