One thing I do not understand is that people will dismiss the F150 yet hop on a SD bandwagon so quickly, not saying you are but it reminded me of something.
Nobody would hesitate to say that a F250 from day the mid-late 90s is great for towing and capable. You look at a current F150 EB dimensions, power, and other things it is even with a 90s F250. The current F150 has bigger brakes, most likely a more capable trans, the same track width, almost the same power stock.
Thats not where I was going, I was just pointing out that the person who commented that the fleet F150's he was running didnt make 200k probably should have been running 6.2 SD's, due to the daily hard use and extended idle times. SD's do have more durable powertrains.
As far as the new ratings, I do think they are overhyped. I have an 07 LBZ Dmax, and the ratings of some new F150's are pretty close to my trucks on paper. Real world which do you think will perform better?
Of course if you live in a city or urban area a SD would be physically harder to manage, gets worse mileage, and isnt as "car-like".
For a new F150 I would lean toward the V8 due to its simplicity and durability.
