Was told that the fuel filters are required change every oil change. Was told that from dealer service department. Must be location specific on costs as have read other places are less expensive. I changed dealers on my last purchase so will ask what they charge. If a bit cheaper, may consider going back to diesel if I ever upgrade. But unless Ram changes to at least a 8 speed, may consider GM with the 10 speed. Every person I have talked to that owns one states it’s a beast pulling 15,000 lb rv’s.
