Bigger cabs often have room for bigger fuel tanks. Smaller cabs may have smaller tanks.

How Far Can You Drive With a Full Tank?
Knowing how many gallons your F150 holds is good. But you also want to know how far you can drive.
Here is a simple way to estimate:

26 gallons × 20 MPG = 520 miles
You can drive about 520 miles on a full tank.
