2008 Tundra duble cab long bed about 16.5 in the city and 17 or so on the highway. Im convinced my dog box is screing me up, so im gonna shorten it a little and see if it helps. When i put my 12ft open fourwheeler trailer on it, i can watch the gas gauge go down..

Its rated to haul 10,000 lbs but i dang sure cant afford to do it if i wanted too
