I drove it to work Thursday, filled up at the gas station 7 miles from my house, 55 miles each way to work, I was sitting just barely above half tank when I got home.

Then there is something seriously wrong with your vehicle.

When was the last time you changed the plugs? The 5.7 requires new copper core plugs every 30k miles..
