Returned recently from a round trip to Southern Florida from Seattle in our 2007 GMC 3500 Duramax packing a Northern Lite 10-2 CD SE. It now has 182,000 miles. Averaged about 13 MPG carrying 4,000 lbs. Did an oil change in Florida (I change it every 5,000 miles). No problems on the trip but after getting home did flush of tranny, transfer case, both differentials and cooling system(I do this every 60,000 miles). Changed engine oil. Replaced both front wheel bearings and belt and hoses(they were all originals). I change the fuel filter when indicated by the DIC. I have found only B5 diesel available in some places, never been a problem. Wouldn't hesitate to do the trip again.
