I suppose so haha. That’s great mileage! I’m looking into a 6.7 right now

I've have 2 trucks, an 2006 F350, 3.73 Dually with a 8'wide, 12' long steel dump bed with 4' sides. It pulls a 14' trailer loaded with mowers and other lawn equipment. It can't get out of its own way. It averages about 5 mpg, we're gonna change out the rear gears to 4.56 at least to help pull the load better and maybe pick up a couple mpg.
The other truck is an 2006 F250 super cab 5.4 with a 3.73 rear. No towing usually, it averages about 11 when its running right which has been an issue lately.

It seems to me that an F250 with a 5.4 should be getting an overall mileage of about 13 mpg. Since these trucks do not have EPA mileage estimates, we can form our own estimates from what we see here.

Thanks,
