Gas MPG for '99 Chevy 3500 Dually w/454 7.4L

[skeedoo]

I just bought low mile, mint condition 1999 Chevy 3500 Crew Cab 4x4 Dually with the 7.4 liter 454 engine off of a friends parents. Here's my question... What kind of gas milage should I expect from this truck. My guess is anywhere from 8-12 MPG. I'm wondering about towing mileage versus non-towing mileage too. Any thoughts?

Usually, when one buys a truck like that, gas mileage is something that you probably don't want to think about.

You're probably right on with your estimate though.

no difference towing or not towing had similar truck for business 10 miles a gallon unless driving over seventy mph.

We towed a dozer with a 1 ton 454 from Michigan to Central Indiana one year and we never passed a gas station! I'm thinking 5 maybe 6mpg if your going down hill. I could only get 9 out of my Hemi, no way are you getting 11-12. I switched over and got a Cummins and get 21-22 highway and when I am towing to michigan with a 33 foot 4 place I got 14.

There's a reason why those rigs have a 43 gal gas tank. If possible, they'd be equiped for in transit fueling similiar to fighter jets
