I personally own a Toyota Matrix 160k miles on it and recently purchased a Toyota Tundra 2012 Limited for my Company. I pull a 7000lbs trailer demonstrating our tools around the country. I get a lot of people ask me how a Toyota does with heavy loads and I tell them I forget that it's even there and I go around the country with this nice show setup. Best MPG on a highway is 12.4mpg. Not bad.
