Big tires, big bumpers, tuner, tool box.............. you have done everything possible to KILL MILEAGE...what did you think was going to happen ? When you do those things your not interested in the mileage your getting, your looking for visual satisfaction...
General maintenance , spark plugs, cleaning sensors.... those might help depending on the age of present.

Is the speedometer adjusted for the bigger wheels/tires?
The extra weight doesn’t help, but driving like a grandparent (especially from stops) with an engine that has a ~3500rpm torque peak with these porky 11th Gen trucks won’t help, either.
If you had 235/70/17 from the factory, you’re off quite a bit. Probably have 3.55 axle gears, now about 10% taller. That will dog things down.

I have an 07 F-150 2wd all stock 4.6 screw. Stock tires. 3.55 rear axle ratio. I get about 16-17 on a trip a highway, and about 14 around town. Basically the same as every Ford truck I've ever owned big or small. If you want good mpg, buy a vw TDI for daily driving and use the truck for work. I don't think there's any way to get 20mpg with a Ford truck until you get much newer. I think the eco boost is supposed to get good mpg but I've seen plenty of people complaining that they don't. Not sure why.
basically, these trucks are just heavy. Then change to wider or taller tires, anything that causes more air drag and it just goes backwards.
I have a 95 f150 5.0 auto 2wd that runs about 13-14 any way I drive it. My 07 is heavier and a little better on gas. I'm good with that!
