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 ...

Went from 12mpg towing a Jayco 15,000gvw fith wheel to 10mpg towing a Lifestyle 18,000gvw fifth wheel with our 2016 GMC 3500DRW. A lot has to do with front cap design and size. Jayco was 8 inches shorter, 6 inches narrower sloped back. Lifestlye pretty much flat front. We drive 62mph with cruise control.
