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!
