From the looks of the tow mirrors I would venture a guess that you did manage to locate a truck with the max tow package option on it.
The F150 is a nice, very nice truck. Then add in that Eco boost under the hood and it turns into an amazing truck. I had a 2013 FX4 Eco F150 for a few months before trading up to my F350 FX4 6.7PSD. If you would like to visit a great forum dedicated to the Eco Boost F150 I recommend F150 Ecoboost Forum
A great warm owners group full of information and assistance when or if needed. It is a very family friendly group.
