I will say 6mpg but there are alot of variables:
What kind of trailer do you want to pull? Drive in the mountains or plains? You going to drive 63 or 85? How much do you idle? |

Cummins or Caterpillar which one is better ?
thanks |
What year is it? Did you mean 550 CAT? Does it have a full fairings, including roof? You also could get an ECM printout, which will tell you what is their MPG is up to date...

I would expect close to 7 mpg as long as you keep your foot out of it. Personally, I prefer CAT. Cummins makes a good engine. Either should serve you well.
