Full sized van boattails?

Related to the schoolbus topic almost... have people put "aerodynamic rear treatments" on full sized vans to see what kind of mileage improvement is possible? I'm curious for those who may have no alternative but to drive such a large vehicle (due to needs to haul cargo or whatever) whats possible.
