The Truck Version of ecoboost has been out for almost 6 years and millions of vehicles. They make a smaller version for their cars. I think that qualifies as proven. The 5.0 v8 engine in the 2016 is a new design
as well and has been around for about the same time as the ecoboost.
I go up highway 421 to Boone, NC it is an 8% grade. I go up it easily at 1900 rpms 65MPH and I mean easily. I am turning 1900 rpms at 75 mph on flatland.
I don't plan on towing anything heavier then 4k or so when I do. If I wanted something for towing 12k I would have bought an f350. That said I have every conceivable towing enhancement on this truck but it came with it and I didn't special order it .
Enjoy your new truck it is nice and certainly an upgrade from the Tacoma you drove , I know it is for me.
