2005 NRC 45' with 515 Detroit Series 60 and 12 speed auto shift. Trailer is a 37' Mathis pivot lift stacker on air with spread axle. This length includes tongue. This in not a new truck and trailer and is not in new condition. It is very nice and to my knowledge everything works. Runs and drives great. Truck has some starches and trailer could use a paint job. Trailer is spread axle on air.
