stabilizer bar...is that the same part as swaybar?
Mercedes sells the Sprinter ((mini)van) in Europe with AND without rear swaybars...the difference of having a swaybar or not on a loaded van is huge, but as long as the van isn't filled with whatever...there is no problem at all...
Nevertheless Mercedes does sell new vehicles without rear swaybars (for whatever (cheap!) reason).
