   After reviewing data from other sites, seems the 5.0 might be the engine to have.  The 6.2 is not fuel efficient, the 3.7 V6 is decent hp, but perhaps not enough torque for those who tow.  The $700 extra EcoBoost gets only 1 mpg more than the 5.0.. with just 5 hp more!  Can you imagine how many years it would take to regain that extra cost?  But...the concern I have now is what some engineers say is the V6 EcoBoost's inherent smallness (fewer cylinders) to dissipate heat created by 365 hp.  Ford limited the speed of the EcoBoost on the Taurus and some are saying the inability to dissipate the extra heat through only 6 cylinders versus 8 in the 5.0 is the reason why!  Is this something I should worry about if I want to buy the EcoBoost, especially in a heavy pickup?  I welcome any suggestions because for the little gas savings (1 mpg) and the extra cost ($700), I worry about the long term reliability

I copied the above from one of the car sites I look at from time to time.  He kinds of sums up my view, plus there are 2 turbos to go wrong.  I'd like to see a small turbo-diesel.

My truck gets around 20mpg - city & county roads, no highway.  If you could get 2 mpgs more than me (22), at $3.00 per gallon, driving 15000 miles per year, you would spend $205 less than me (about $3.94 per week).    

(Now at home...finishing comments )

With the above said, I am impressed with the horsepower and torque of this motor.  Really nice - the peak torque is low in the rpm range (about 2000, if memory serves).  So, the numbers say it should tow well.  The downside is EPA 16/21mpg (if memory serves), 2 turbos to maintain and the additional $700.
