I'm running a 43' stretched Columbia chassis with 450 MB and 10 spd Eaton autoshift. Driving 70 with no trailer it will do 10mpg (running aprox 70mph). Have logged less than 5k miles so expect the milage to go up when it loosens up a bit.
The Eaton auto shift is great but without a trailer the lower gears are overkill. Better to put it in the manual mode to upshift from a stop.
