Realilistic mileage with a fifthwheel.
Just curious what kind of fuel mileage I can expect with a fifth-wheel. 1ton 4x4 duramax srw 36 Ft. 13Klbs fifth-wheel. I realize weather, road conditions whether it is flat or hills or mountains ...

10.5 is the HIGHEST hand calc i see towing at 60 near sea level with no winds. My tanks range from 7.5-10.5.
I am talking AVERAGE over many tanks, NOT using the display.
NOT calling you a liar but this seems very unrealistic even with you I am guessing grossing at 26k or so compared to my 33k.
I am wondering what makes the difference?
Our trucks are mostly the same. You mentioned your higher weight. Other factors might be that you (I think) have two more tires (triple axle) and your FW is taller at the rear (less aerodynamic).
