Surprised no one has mentioned the Mercedes Sprinter van now available in AWD from the factory. In the past, they had to be converted aftermarket. Mercedes got smart and just integrated the aftermarket conversion (sourced from Australia, I believe). Personally I am in the Subaru Outback camp, but the vans are intriguing.
