Hey. Like anyone else im trying to lower costs. My highest cost is gas and its about on avg 3.40 where im at and diesel is about 3.75. Im always towing everyday a 12ft open trailer with 2 ztrs and relevant equipment. Currently im driving 2 different trucks a 2004 f150 33 gallon tank and a 2007 tundra with 22 gallon tank. On avg I get 280 out of the tundra being full and the f150 about 350-400. Would I be better served in buying a diesel truck to use for work? Whats the avg mpg you guys that have diesels are getting towing? Or perhaps getting a smaller truck such as a 4 cyl tacoma or even 6 cyl small trucks as like rangers, canyons etc.. what are your guys thought.
