Re: 4x4 Sprinter Coming in 2015!
Advanced RV just used a stock photo of a 2500 4x4 since they don't actually have a 4x4 yet. Nor does anyone else since they don't go into production until after the first of the year at the earliest. Note the European license plate. I believe the dually will go 4x4 also. But, I don't know for sure. There hasn't been any specs published yet that I can find.
As for off-road as in "serious" I would think one would have to be a little off-rocker considering what you carry inside a Class B. I don't believe anyone thinks of it as a Jeep and Mercedes Benz has never suggested that.
