David, please excuse me asking again, but how slow do you drive an Axis 24.1 in order to average 12 MPG? That’s up there in large van territory; which is excellent but way above the mean.
Since your 24.1 was likely built on E-350 stripped chassis, have you looked at “Axle” designation on door sticker to see if you have 4.10 or 4.56 gears? Even taller gears doesn’t explain 12 MPG when most owners report +/- 10 MPG at best as an actual long-term average. I normally dismiss single-tank results because conditions may have been abnormal (like tailwind, downhill, etc.), but your average over 5,000 miles is very unusual.
If I recall correctly, you don’t tow and rarely use generator, correct? Others that do likely use more fuel, but it’s hard to account for 20% difference.
