There WAS a discussion on this - quite a while back and I entered in on it too. It's something to do with the way Ford has set up torque in 2nd gear.

I think there's a reduction at either low speed or low RPM to help you get moving on "slippery surfaces". Remember the old trick of starting in 2nd on ice to avoid spinning the tires? (Naw, you're too young). But anyway, above a certain speed or RPM, full torque transfer comes in and you can pull like a bandit!

I pull my 3600# trailer up over the high Colorado passes (11,000+ feet) with the transmission locked in 2nd.
