10 speed F150 axle ratios
I'm considering a 10 speed F150. My '13 3.5 Ecoboost 3.55 axle 2WD Supercrew short bed is darn near perfect for my one and only cage transportation and tow vehicle. It performs very well. I have weigh...

Due to how much low end torque the current Ecoboost has, it hardly spends any time below sixth while cruising unloaded. It would hold gears on hills that would make most N/A V8s drop down a gear or two.
Maybe yes, maybe no. "Shift scheduling" is somewhat of a black art (or maybe I should say an unlearned art) on these high gear count transmissions (I actually wrote software for shifting a 4 speed - that was not too hard). Customers don't want a "busy" transmission (constantly shifting up and down) but also don't want to have to stomp on the pedal to get it to "kick down).
The shift schedule will be very different in "tow mode".
Well, there is no maybe about it from my real world experience. I owned a 2011 F150 with an Ecoboost and it does not spend a lot of time in 4th and 5th like you assumed. I encourage you to drive one and then go out and drive an N/A V8 right afterwards. I know from experience that you will find that the Ecoboost will hold gears better than most other V8s due to it having considerably more torque and horsepower available at 2,500 rpm. Those other V8s would have to rev up past 4,000 rpm(requiring multiple downshifts) to equal the amount of torque the Ecoboost makes at 2,500 rpm.
