how many gallons of gas do our tanks hold

[Longhorn Man]

3 trucks owned here;
69 1/2 ton 305 V6 short/fleet 2 wheel drive
70 3/4 ton 350 longhorn 2 wheel drive
70 one ton 350 longhorn 2 wheel drive

All 3 had 20+ gallon tanks.
I drove to the gas station once and put 21.75 gallons in the C/20 longhorn.
You can bet the pumps are pretty accurate on weights and measures... the gas stations make so little per gallon in profits and the fines are so huge for 'tampering' with the pumps that it just isn't worth it.

I'm guessing I had more in my tank than I thought. But I've never been one to push it when it's getting down to empty.
