1993 gmc sierra dually

Custom 350 swapped lowered gmc sierra crewcab dually. Truck has been in wisconsin its whole life but in good condition for age, only minor surface rust in usual areas -rockers/wells. Floor and frame are solid. Odometer is not actual due to engine/interior swap done by previous owner. Aftermarket exhaust, back 4 tires are almost new, recent oil change and differential flush. Lowered about 2 inches on drop shocks/springs. A/C does not work. Could use a little tlc but overall good running truck.
