This monster was set up to tow up to 30k lbs. and everything isabsolutely perfect. It is a 2 wheel drive because is is designed for towing not offroading. It is a one of a kind truck with great miles and set up to tow the 40 foot boat out to the lake with the family inside comfortably watching satelite television in the back seat. The suspension is set up with the fully adjustable King Kong Shocks so the ride is like an Escalade the air bags are adjustable so if it feels a little soft just firm it up and vise versa. It is powered by the Cummins ISB 230 with 230 hp and 520 lbs of torque. It is backed up with an Allison 6 speed transmission. The interior has full leather seating and a crazy stereo system with 2 subs and a touch screen navigation and DVD player with surround sound and Sattelite Television.
