RAM Cummins fuel filter change interval

I buy a case of filters at a time and change them every 10,000 miles. Cheap insurance.... have you ever had to replace injectors ? If you ask someone that has never owned and maintained a diesel truck they all say ....fuel/gas filter ???? I've never changed it.... same with transmission fluid.....what do you mean have I ever changed it ? Do you need to change it ? One thing is for sure changing your fuel filter will never hurt your diesel motor.
