What size motor? I pulled a 9000 pound 5er with a 2010 f150. I was about 800 pounds over payload and I still had lots of suspension left. Ford is built to tow and haul, unlike Chevy and dodge, put them 800 over payload and their suspension will be maxed out frame on the stops, lol! If you got the 5.0 will struggle if you have hills, 3.5 eco will get about 7mpg but won't struggle, if you plan on towing far or often I'd get a f350 but a couple hundred miles a few times a year you'd be fine. 5ers pull a million times nicer than tts, no sway at all.
