    I have a 9200 with a Cummins ism and a 10 speed autoshift, when I pulled a flat I could get 7-7.5 mpg. Now that I pull a connie I get 5.5-6 what can I do to improve it?

    I have a 12.7 detroit 470 pre egr,13 speed double over, not turned up,im guessing it has something to do with the Aerodynamics of the trailer,Flats get decent mileage if not loaded too heavy

    That's a good question. Were you thinking Turbo wing??? Another option is getting a roof fairing.

    The truck had a bubble roof and I would rather take a cut in economy than put it back on.i don't think one of those big turbowings would look good on it. I was thinking more like a smaller fiberglass wing like I've seen on some trucks.
     
    The Challenger Thanks this.
