What is the average MPG the 2001-2003 Ford F-250's get now a days?

I'm going to get a 2001-03 ford f-250 diesel v8 for my first vehicle in a few months. And i'm also thinking about moving out of my parents house and i'm trying to figure out what MPG the truck will get to figure out what I will spend a week (i'm trying to figure what i'm going to spend weekly and monthly on bills that includes fuel) I know the MPG is different for trucks (even the same kind) and it varys between MOD's put on the truck and the driver. So what are you guys getting mpg wise on your 01-03 for f250's? Later I will add dual stacks and an 8inch lift and maybe a tuner. But that's a few months after I get it(anyone know what mpg it will get with those mod's?) anyway. Lets say I drive normal (not reckless and that fast) and I buy the truck with an already 6inch lift and mud tires? What MPG will I get? And what will be the cost per week driving this truck? If I drive it every day?

Used to drive a 2000 7.3 powerstroke. I averaged… Roughly 17/18 mpg, albeit it was bone stock. I'd imagine you'd yield around 15 or 16 with the lift and tires. How much it'd cost you weekly depends on the mileage, and how many miles a week you drive.

Same as it was in 2001-03
