2013 F150 Towing?

I just checked our sticker (F150 super crew, ecoboost, short wheelbase) we have the standard towing package with the 3.55 rear end. Ford says we hav 9600 lb towing capacity. Our Kodiak weighs 6600 dry. I estimate we are really about 8,00 lb loaded.

This summer we crossed many mountain passes and some steep hills . No problem towing.
