I have an old F250 triton V10 that tows fantastic, its a 2000. I also just bought my new daily commuter truck, a 2011 V6 twin turbo F150 4 door ecoboost with tow package. This truck ROCKS. Hauls the 2 horse gooseneck as easily as the big truck, and tons smoother, plus about 19 miles per gallon for daily driving as opposed to 12 in the big truck. You have to get the 6 foot bed to fit a gooseneck hitch in the bed, so its pretty long - but I love this truck!
I was VERY skeptical until I hooked my trailer to it... and you have to accept limitations, it will never safely haul anything bigger than a two horse gooseneck, but since thats what I have it works just fine.
