Like with most things there are pros and cons, and in the case of sway bars it seems to me that you may be able to improve on-highway performance but at the expense of off-road performance. Unless you go to a disconnectable sway bar setup wouldnít it reduce your axle articulation for off-road driving? Or are you worried that the van will tip over during off-roading?
Itís not even a given that adding a rear sway bar will help on-highway performance. It depends on specific circumstances so you canít go by what others have experienced unless very similar vans. A sway barís main function is to increase roll stiffness which should reduce the amount the van leans on turns, but that loads tires differently. As an example, a van could end up leaning less but having too much oversteer which is not a good thing.
My personal tendency is to not try to fix a problem unless Iím certain that I have one.
