I was just pulling numbers out of my head. Your logic seems more correct.
You also make a good point that the 2014 getting the 23mpg on the highway is not what I should expect with a different rearend.
I've been doing lots of reading on the max payload option with the F150's. I spec'd out an Ecoboost with max trailering and max payload. Payload of 2620 like I have it. That is exactly the sweetspot I was looking for!
Sat in the F150 at the dealership and did genuinely like the truck better than the Chevy.
Now the kicker...I didn't mention that I qualify for the "A" plan with Ford. My mother in law put in 30 years in Detroit. With that plan and the current incentives, plus my trade, it brings the purchase right down into a comfortable spot.
I really like the idea of the torque being available without running up the rpm's. A little cautious of the more technical engine though. More reading.
Does any other manufacturer have a package that brings payload over 2500lbs in a half ton? I didn't see it.
