i'm looking at a 99 2500 with 24valve cummins. Couple questions i was hoping you folks could help me with. Wat kind of mileage do these trucks average? This truck has 192000km or 119000 miles. Seems like a pretty decent amount to me. and also i noticed that when i let off the pedal in the 5 speed it almost seems to have slack in the drivline cause there's a pause then it slows down hard. In my 01 f-250 diesel when i let off the pedal it's real smooth. Is this a dodge thing or a point of concern?
