I can avg 22mpg hwy with 3.73s but mine is 2wd and i drive 65mph. Combined avg has been in the 18 mpg range. 11-12mpg toqing 5500# travel trailer. The 3.55s will lower your tow rating a few thousand pounds or so. To me the extra smidge of mpg isnt worth the trade off in capability.

I tend to keep my vehicles for a long time so long-term reliability is very important. To that end I was originally set on getting the 5.0 as there are just too many serious problems that have been reported by ecoboost engine owners (just spend some time on the 2011+ engine related forum here or the e150ecoboost.net forum). The whole CAC debacle, fuel oil dilution, stretched timing chain and other issues. It's not so much that a few owners experience these problems but it is that they are experiencing them with relatively few miles and Ford seems either unable or unwilling to adequately fix them. And there have been more than a few cases where it appears Ford and dealerships are not even standing behind their own powertrain warranty, saying symptoms are "normal" - until the timing chain breaks out of warranty and you pay up to $17,000 to replace your ecoboost engine (in Canada).
So why did I order an ecoboost myself? Partly because I want a high end vehicle and that is the high-end engine. Partly because it goes faster and supposedly gets better mileage. Max. tow was also appealing to me for a time until I discovered how it did nothing for payload figures on the 2015. But mainly because I became convinced that there is a preventive solution to most of these issues, that being a dual check valve catch can. Something that can compensate for Ford's poor PCV implementation that only evacuates the crankcase at idle and deceleration and can prevent the often significant quantities of really nasty gunk from being digested directly by the engine.
But now I have definite concerns that installation of a catch can means voiding my warranty. A few Ford dealerships are installing these catch cans themselves while others are voiding warranty. Not fun for the end consumer.

I personally think I will sleep a lot better at night with a 5.0 w/ 100k on it in my garage than an EB. That's why I'm 90% convinced I'll get the 5.0. Both motors are so good in terms of power delivery and performance that both are "premium" engines to me.

From an article on Torque News regarding the 5.0:
"This extra power comes from a new intake manifold design, a new camshaft setup and new exhaust manifolds"
I believe this is the same thing I've read on other articles.

I had the two valve 5.4L V-8 in my 1997, the 3 valve 5.4L V-8 in my 2010 and currently have a 5.0L V-8 in my 2014 and was seriously considering getting my next F150 with the 3.5 V-6 EcoBoost but the "canned" exhaust sound track thru the stereo that goes with the EcoBoost is a deal killer for me. It's akin to corking the bat.

I agree, the fake engine sound is down right silly. Not sure I would let that completely turn me off on a truck purchase, but I guarantee I would be finding a way to disable it!

I have to disagree on mpg the fellow who bought my 2013 Eco who lives right beside me and is a close friend,is getting 14 mpg on it and on basically the same roads I'm getting 19.2 on my 5.0. And a co worker has a 14 Eco and travels flat interstate comute is getting 14-15 mpg and either is very happy about it.
