First decent trip and pretty surprised at the mileage...

In 87,000 miles in a 1994 35' Bounder pusher with a 190 HP Cummins, I averaged 10.00 MPG. Sometimes I'd get 13 MPG, other times, 8 MPG. But the average was 10 MPG. I kept very accurate spreadsheets over 12 years of full timing.

I think the small engine, pushing 28,000 lbs and my light foot helped keep it that high.

In my present RV, a 2002 35' Journey, over just 7200 miles of my style driving, I'm getting 8.1 MPG average, hoping for more. This RV weighs 8,000 lbs more than the Bounder.

It's a process.
