I've heard that this van's meant to replace the Dodge B-series full size vans. I also heard that they're marketing them under the Freightliner name instead of the M-B name in the United states for psychological reasons. Their primary target is apparently going to be commercial/sleet sales, and they're worried that the companies won't buy the vans with an M-B namebadge because the companies' customers may see the M-B logo and feel that the companies spent more $$ than they should have on the vans.
Kinda weird, but hey! If they bring it over here with a diesel, I won't complain...
