I know that Enterprise has ecoboost f150s in their fleet, but they won't let you tow with anything in their retail fleet. I will tell you though, I rented a 5.0 v8 crew cab XLT for a trip to VA and found it to be a fantastic ride. Hauled my bike (diagonally) with the tailgate closed, and accommodated my wife, kids, dog, and I very well while averaging 19+ MPG highway. If I were buying one, I'd buy an Eco-boost XLT with 4WD and the longer full-size bed. That extra foot or so in the bed makes a HUGE difference.
