RAM Cummins fuel filter change interval

Since they are a little pricey, I don't want to do it any more often than necessary.

I do mine at 15,000 and get the filter at Genos Garage. Price is very reasonable in my opinion (less then $20) and only takes ten minutes to change. The easy self priming system is almost effortless. Maybe the later models have a more expensive filter. Maybe the OP is getting the price quote from a Dodge dealer. Genos price for a '12 fuel filter is $47.
