Here is my dilema, i am for surely buying a 2012 f-150 proabbaly this week. Here is what i am going to do with it. Roughly about twice a month i will be hauling my 26 foot travel trailer and my 2010 yamaha grizzly to the cabin which is 2 hours away from me and mainly flat with a couple of small hills. My total pulling weight loaded up might get around 8000lbs. I have the ford brocure in front of me and the ecoboost crew with 3.73 will pull 9500lbs and the 5.0l with the 3.73 will pull 9200lbs. Is the eco worth it or should i get the more trustworthy 5.0l????
