Just wondering what kind of mileage figures I might expect with a single axle dump truck. I am looking at buying a 2008 Topkick or an Acterra with an automatic and 12 & 21 axles and 200-220 hp. If you know fairly accurately what you get for mileage I would appreciate the info for my number crunching. Looking for loaded mileage, or pulling a machine on a trailer. Thanks for the help.
