I've looked myself, but am still wondering how much weight my half ton F150 could tow? It is a 2007 Supercrew Cab 2wd with the 5.4L V8. I am trying to understand what all the numbers and letters I've come across actually mean and how much my truck can tow, and tow safely. And what would the max length be to tow safely? I've heard 25-28ft. or less for a toy hauler?
