There are many, many ISB's that do that 10 MPG.
My 5.9L has 660 ft lb toque + with a Banks Power Pack and Allison 6 speed
Weight pulling a toad is around 26K.
Yes it is probably the smallest
Diesel most commonly used in Class A DP or puller. But the Toque it puts out, would be very big
to any gas engine in a Class A.
I have a spreadsheet with every drop of fuel that has gone into it since 8/02
Lifetime average(7 years +) is 10.215 MPG driving from Maine to Florida to Colorado and all states in between.
Just to check what it can do. Last summer(09) I held my speed down to 55-58 MPH 98% of the time. Average from May to September was 10.781 MPG. All on spreadsheet.
All roads in life time of spreadsheet included downhill, uphill and flat.
Sorry have no record on what percent of each was used.
I also had a spreadsheet on my last gas Class A with a 454 Cu in GM motor. It's lifetime of the 10 years I had it. The MPG average was just under 6 MPG. It also traveled almost the same roads & states as the ISB has.
The difference saved in fuel cost between my old gas and the ISB.
To me has paid for all maintenance cost for the ISB.
So that saying that most say, about diesel maintenance cost is higher then gas. Are not really true to me if you include fuel cost per mile.
Your experience may be different. But there is nothing wrong with that.
If you don't want a diesel. Don't take one on a test drive.
