I've got a 2012 ecoboost 4x4 with the heavy tow package.It pulls and stops my 9500lbs 24ft enclosed trailer like a dream.I put air bags on it to level it out.Now for the bad part,with the p tires that come on it is bullshit.It needs 10 ply tires and will have them soon.It gets around 9 or 10 mpg doing 75mph.The trailer does move around a good bit.We normally pull with a 2002 8.1 liter chevy dually which is stable at what ever speed you want to pull at.But as far as power,the ecoboost will hands down out pull it.The water and trans temp is not a problem.The highest trans temp was 204*
