two wheelbase options (144", 170"), two roof heights (standard 60.6", high 72.4"), three lengths (Short 233.3", Standard 274.2, Extended 289.8"), and two weight classes (2500, 3500). 3500 models have the option of dual rear wheels or extra-wide "super single" wheels in some, but not all, markets. Neither the 128" wheelbase nor the rear super single tires are available in the United States market. The US cargo version are reassembled from kits in an assembly plant located in Ladson, South Carolina, while the passenger models are imported directly from Germany. The second-generation 906 was produced in Argentina only for export markets—except Mercosur markets (Brazil, Uruguay and Paraguay)—from 2007 until 2010, but in 2011 announced new production of the second generation in the Centro Industrial J. Manuel Fangio, in Buenos Aires with the brand new OM 651 engine (also local made) and exported to the rest of America (including Mercosur markets). Since 2012, it is manufactured for the Mercosur and 40 other countries. 70% of its production is exported. Production Mercedes-Benz Sprinter was built in Daimler's Mercedes-Benz Düsseldorf and Ludwigsfelde production plants. For the second-generation Sprinter marketed in the United States, to avoid "chicken tax" import duties, the cargo version was disassembled partially, shipped to the United States, and reassembled at a plant in Ladson, South Carolina (near North Charleston), in a process known as semi knock-down assembly (SKD), starting in June 2006; the passenger version continued to be imported as a complete unit. The Ladson factory previously was used as an American LaFrance factory for firefighting trucks. The previous SKD reassembly facility in Gaffney resumed operations under Freightliner Custom Chassis Corporation. The Ladson plant was known as DaimlerChrysler Manufacturing International until the parent corporation was dissolved; importation and SKD reassembly of the Sprinter cargo van continued at Ladson under the auspices of Mercedes-Benz Vans, LLC. Between July 2013 and the end of May 2014, Mercedes-Benz Vans sold around 134,000 units of the new model of Mercedes-Benz Sprinter in Europe and North America. The production version of the Mercedes-Benz Sprinter-based Volkswagen Crafter by Mercedes-Benz Vans was set to end in 2016. A class action lawsuit was filed in California state court against Mercedes-Benz alleging the defendant has sold Mercedes-Benz Sprinter models 2500 and 3500 with water that leaked from the roof air conditioning unit into the passenger area. The leaking air conditioning unit was also discovered on Dodge Sprinters made by Mercedes-Benz
