I used to tow with a Tahoe that got about 8-10 mpg most of the time on flat roads as most of my towing is done in Florida. I now use an F150 ecoboost, which gets me a little more than 11 mpg when towing. The mpg was not my first concern for towing, it was the power. I know when I tow, if I need to kick it in the backside, there is plenty there. The truck bed was also a consideration for taking bikes and or extra gear. Good luck with your ecoboost and just remember as long as your happy with it that's all that matters. What everyone else uses is their choice to make them happy and yes there can be some real sarcasm on many of these blogs. Happy camping everyone.
