The Kenworth T2000 was one of the most aerodynamic trucks made, but no longer produced. This same fleet of trucks we installed Rigmaster units on are 10 Kenworth W900 models, one T600 model and one T2000 model. The driver of the T2000 loves his truck because it not only has a "car like" interior, but gets the best fuel mileage compared to the W900 models.
