I had a 1990 Winnebago on a P30 chassis with a TBI 454. It was 31 feet long and weighed (purely an estimate) around 13-14K lbs.
I got 6.5-7 MPG if I ran on a cool day (ie temp below 70) or at night without the generator going. On a hot summer day (temp above 85) with the generator, I'd get closer to 6-6.5 MPG.
