I tow a cargo trailer, roughly 7500lbs, about 30,000 miles a year currently with a 2004 f150 5.4. I am looking to upgrade this year. Thought I might get a superduty with the 6.2. I am self employed and gas mileage is a consideration and it occurred to me that the lighter f150 with the 6.2 would get better mileage, is that a fair presumption ? I have been reading about the ecoboost and I understand that it is good for towing, but would it be better than the big V8 ? love to get some feadback on this.
