I have a 2001 Monaco Diplomat, 36 ft, with a 8.3 Cummins. I never really followed my fuel consumption for the first years but I believe I was getting about 11 mpg. I had the rig into commins for some work and they messed with the computer. Now I am following my mileage closer and am only getting about 8 mpg. Does anyone have a similar rig that can tell me the milage they are getting.

I also have a 2001 Knight with the 8.3 and have driven it for about 25,000. My fuel consumption is anywhere from 8 to 10.5 mpg. however, my average is about 8.7mpg.
