We towed a 2003 Ford Sport Trac until last year when we replaced it with a 2014 Ford Flex. The ST was probably the least problematic of all the toads we have had over the years. Not all ST's are towable. As mentioned; follow the user's manual, but be careful. Not all manuals found in vehicles are for the said vehicle, so do your research. Remco towing as well as the FMCA dinghy guides help. We had to purchased a "neutral tow kit" which was just a wiring pigtail that plugged into the transfer case to let you know when it was freewheeling. It didn't physically do anything, it was just a light. Ford, I understand, quit making that available and some people managed to rig up their own using parts from Radio Shack.
We traded ours when our mechanic of many years told us the timing chains (3) were starting to rattle and that is an expensive repair. It requires pulling the engine. Done before they break is cheaper than waiting till they do, but it is expensive regardless. She had 167,000 driven miles and another 100,000 towed in the years we had her. A good serviceable truck we were sad to part with, but the "Oster Toaster" seems to be stepping up and filling the void.
The newer ST's are heavier than our '03 so we went a different route.
