The Sprinter is up against two well established players, the Chevrolet Express, GMC Savanna and Ford E-Series. The E-Series is the king of the segment, accounting for roughly 50 percent of all full-size van sales. It's also a favorite of upfitters, thanks to the Ford's total and complete lack of a redesign in the past 15 years. The Express is not quite as popular, but is a newer platform than the E-Series. The Sprinter's advantages are its much larger cargo volume and palette-friendly loading.
