I bought another vehicle last night. Gonna sell the Burb and use the new one as my daily driver tow vehicle. Its a 1997 2500HD 2wd Chevy. Has a Vortec 350 and just rebuilt(not more than 5 miles on it) 4l80e. 3.73 rear gears, anyone have an idea of what I can expect on gas mileage with a good foot? I'm hoping for like 15 but not really expecting heavily. It would be nice to have my first vehicle since I got my license that gets more than 10 mpg.
