Yep

Granted im a prerunner but i also have a lift, an extra 400ish lbs between sliders, front bar, bed cover, blower, and tools.

I averaged 320 the two times i let the gas light come on.

Otherwise i NEVER run below a quarter of a tank.

Mpg will vary with fuel type used (ethanol content really makes or breaks). Also keep your gear boxes filled with synthetic (unless u have a 2009 or above trd sport, those seem to prefer dino in the rear diff due to clutch packs).
