I would have kept the Tundra over the f150 any day.
Fords are known for catching fire.
I'd have to see objective proof of this one. Especially considering that this very board just featured a T4R that burnt to the ground due to a transmission fire.
Stepped up engine selections yes, but the ecoboost may make good power but hook up 11,000 pounds and you will see how eh it is. Plus only loaded with ~6,000 pounds is gets 8 MPG hwy.
The mileage is due to it being a twin-turbo V6. Any twin-turbo V6 will get nowhere near the towing mileage that a similarly equipped V8 will get; pretty much all the reviews say this. In short, they all say that if you're buying the truck to do pretty much nothing BUT towing, go with the 5.0 or 6.2. Otherwise, the Ecoboost will be more than sufficient.
As far as 'eh' factor goes, depends upon how you look at it. From what I've read online (not withstanding the occasional "My truck only got 1MPG towing a trailer full of feathers downhill!" reviews), they're both equally capable of pulling the same weight. Friend of mine owns an Ecoboost and regularly tows about 7000 lbs; he gets about 11MPG. Maybe not quite as good as the Tundra's 5.7L, this is true; but unladen, his mileage is definitely better than the Tundra's. So your mileage may vary. *shrug*
Past this, you're correct - it's opinion and personal experience. I've owned a Ford Taurus that was *THE* biggest POS ever made. However, I've also owned 2 vehicles (2008 Ford Fusion with 65K, and 2004 F150 with 147K) that are excellent. The F150 has yet to have ANYTHING happen to it; with the old 4.6L V8, it still gets 19/20MPG (which is NOT normal lol).
For the record, I'm not making an argument that Ford is better than Toyota; after all, I DID just study SUVs for months, and decided a 4Runner couldn't be beat.

I AM making the argument that Ford has made huge strides in reliability and capability.
