I would absolutely NOT do it. I drive an F350 to pull my 4 horse. I had a bad wreck a couple of years ago when another driver turned her SUV into my truck while I was pulling a trailer. You need to do everything you can to stay safe and a F150 aint it. I also would not pull anything except a gooseneck for horses. My flatbed bumper pull utility trailer fishtailed once and yanked me 360 on the highway.
