This International is a custom conversion done by 2-L Custom Trucks. It is from the 4400 series with the DT530 motor. A True International motor with many more miles of service left as it is rated as a 650k to 800k mile motor. It has the Allison 6 speed automatic transmission. This is also pre DEF. No DEF needed. A cost savings. We have the original build paperwork as well as all other service work performed. Air Ride suspension as well as air ride 5th wheel. The hitch alone runs about 4,000. Onboard air compressor for filling up your toys or tires. New steering tires as of last year. Remaining are in good condition. We have used this to haul our toy hauler RV. It was custom hand pin striped to match our RV at the time by the famous Jeff Dahstrup. Please call with any questions. I drive for a living so I may not answer.
