1999 was the first year of the “Sierra” and it was truly remarkable. This model (1999-2006) Sierra quickly became the working man’s best friend. Its reliability was in a class of its own and that made it the perfect multi-use rig. At Truck Brigade, we enjoy customizing each vehicle to fit the individual’s needs.
