We reported in January on General Motors' planned plant closure in 2012 in preparation for the next-generation of Chevrolet Sliverado and GMC Sierra trucks. The rolling closures will affect several plants with total idle time adding up to more than 20 weeks, prompting some dealers to increase inventory to compensate.

GM's fullsize trucks are the oldest designs among the Detroit Three, with the Ram receiving a comprehensive refresh for the 2009 model year, and the Ford F-150 getting a major freshening in and all-new powerplants in 2011. The Ram 1500 will get an additional update for 2013 with a new eight-speed transmission and the 3.6-liter Pentastar V-6 as the new base engine. The only older fullsize on the market is the Nissan Titan, which debuted as a 2004 model, and remains largely unchanged since its introduction.

Included in the plant idling plans is GM's Arlington, Texas assembly, which builds the Chevrolet Tahoe, GMC Yukon, and Cadillac Escalade models. The fullsize SUVs are scheduled to be redesigned after the launch of the new fullsize trucks, expected to arrive in dealerships in spring 2013 as 2014 models.
