We have a 27HFS and pulled it with a F150 5.4 4 speed with 3.55 ratio. Power was not a big problem as long as you are patient but I started getting rear end shudder after about 9 months of towing when turning a corner from a stop. I traded for a 2500 HD and have never been sorry. The half ton would pull the trailer nicely but when we got the heavier truck, we realized just what a stable pull feels like. Don't make the same mistake I did. As 10X says, "not enough truck".
