My TV. 1999 GMC ¾-ton Sub 4x4 with Vortec 454. She gets 10 mpg empty and 9.9 loaded with my car hauler, either empty or fully loaded!

I also can't see spending $$ on a new TV when this one runs fine, pulls what I need, and only sees 5K miles a year.
Just swapped on the new Duratracs, 285/75r17 on the Hummer wheels back in December. The coolant under the truck was from a fresh coolant change/system bleeding.
