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 ...

Not a 5er, but my TT (over 10,000 pounds) and length (35.5 feet) would be a comparable tow as far as fuel mileage. On average my 3500 Duramax Duly gets 11-12. Which I don't understand sometimes, because when traveling through the mountains of Kentucky, Tennessee, West Virginia, and even the Black Hills of South Dakota, it will get 13-14 in tow mode, exhaust break mode, and cruise control! Go figure!
Same here with a '03 2500 Dodge/Cummins 305/555 HO NV5600 3.73 gears pulling a 11200-11400 lb 5er in sig. The trailer is a old '97 with a flat square front corner profile.
Every trip we make to NM/CO/UT/WY mountains and passes the Cummins gets a good 1 to 1.5 better mpg than in western OK/KS/TX plains (pencil figures).
