Just took our new (to us) 39' Journey on the first trip. Ran for 580 miles and measured fuel consumption. I am well aware of the difficulty in measuring MPG in one run--chances of error in filling tank, writing down something wrong, head or tail winds, hills, etc. But I'm slightly pleasantly amazed at the MPG we measured. Flat ground, 95% hiway driving, 2003 Journey with Cat 3126 330HP engine and Allison in economy mode, very little idling, no gen run. Tires properly inflated, pulling 3000# sedan toad, driving about 65mph on cruise, pretty sure I properly filled tank at beginning and end. 580 miles and 50.1 gallons. Or 11.5MPG. I am not sure what I expected, but certainly not over 10 MPG. Is this reasonable? Next distance run is not until January. Our last motorhome was a gas adventurer and averaged probably 7MPG.
