    Local city work, 75-80k, 69mph, flatbed, some mud and gravel and definitely snow but not many hills.

    Fleetwide fuel economy was 7.3 mpg last quarter on summer fuel, with 51% deadhead (turn and burn). I want to do better. We have a couple Macks with RAR's in the high 3's like the rest of the fleet. I'm wondering if a more downsped setup would stand up to the type of work we do. Like I said, city/traffic, construction sites, snow, etc. and heavy steel loads but nothing over 80k..

    Anyone recommend a Mack setup and reasonable MPG target for this type of work?

    I think a down sped truck may cost you economy in your application, more stop and go would be less efficient with the tall gears used to down speed.
