Interesting how times have changed 5 years ago an ecoboost thread would end up with half the replies warning of imminent ecokaboom, with slaughtered f-150's lining the shoulders of interstates all over this country.
Now we have ecoboost threads saying, they tow in altitude great, and generally perform as advertised, though without the eco part of the equation while towing or hot rodding. I guess those who predicted massive failures got tired of waiting...
For OP, I think you've gotten some really solid advice in this thread, Best of luck with whatever you decide.
