I have a question, im looking for a truck to tow my truck, i got a 18ft car hauler with dual axle and brakes, im looking at F-250s, i found a 1999 7.3 powerstroke with 230000 miles, my question is, what would you expect the engine to last in normal operating conditions? 300,000 or 500,000 miles? or would that mileage be too high to think about buying?
