comrades - 2500 ram tradesman cummins 2018 . i changed my filters at 14,600. i need to go from colorado to chicago shortly, because my pop is not doing well. current miles on truck is 27,000. should i change the fuel filters before i leave or when i get back? 1000 miles exact each way. i dont know the probability of the truck thinking the filters need serviced when they get close to the due date via miles driven. thank you in advance for your thoughts/advice. cheers, chris
