My bus with 8V-71T with air to air intercooling and V730 gets 4.8-6mpg.
My truck conversion which weighs 10,000lbs more than the bus with 3406B 400hp and HT740 gets 6.3 Good Luck, TomC

The 68 MCI 5A that i used to own has an 8v71 and Allison MT644 transmission. Got a high of 8.4, a low of 5.9, and a 7.24 average over 85,000 miles.

My little 10,000 pound bus with the 5.2l Isuzu turbo diesel averages 15 mpg.  A little less with the toad and a little more without.

I know, I know---Damit Jackie shut up!  But look at all the fun we have in it.

6V92 with Allison HT 740. Last trip if I did the math right was high 8 per gallon, but it was from 2000 feet up where I live in N Georgia to Lakeland Florida. All down hill or flat. I don't tow. And Ok...maybe a tailwind.
When 20 of us have answered, Sandra is going to come back on and tell us that even though she is full time, they had to buy fuel for her skoolie ( and nice bus by the way) back in November....
