The 2011 Chevrolet Silverado 3500HD is offered in regular cab, extended cab or crew cab body styles. Buyers can choose between the conventional single-rear-wheel (SRW) or dual-rear-wheel (DRW) configurations. The regular cab and extended cab are only available with a long bed (8 feet), while crew cabs can also be had in standard bed lengths (6.5 feet), but only with SRW trucks.
