Commercial Customers Test Pre-Production 2011 Ford Super Duty: To supplement the rigorous durability testing performed by its own engineers, Ford has asked selected commercial customers with severe-duty applications to test pre-production models of the all-new 2011 Ford Super Duty for six months before the truck goes on sale. Reynolds Asphalt & Construction Co. of Euless, Texas, took delivery of a 2011 Super Duty F-550 4x2 dual rear wheel chassis cab upfitted with a mechanic's bed to use as a service truck for the company's heavy-duty equipment. The F-550 will carry welding equipment, compressors and a crane body to jobsites for repairs on Reynolds' heavy equipment, including pavers, rollers and graders.
