Just finished a very cool roof basket install on a fleet of 2008 Dodge Sprinter vans for GMVS, a ski racing acadmy in Vermont. It's kind of a custom gear basket setup because it will be used to carry a lot of skis. The cool thing about the 2008 Sprinter vans is thay they have factory installed roof tracks so it's very easy to attach either the Thule 430 Tracker II roof rack system with the TK1 Tracker Kit or the Yakima Control Tower roof rack system using the LP1 Landing Pads (this is the setup used on the Green Mountain Valley School vans).
Here's some decent pics of the Dodge Sprinter van ski basket rack install...
