 My truck is an 2004 F-150 STX version 4.2 and 5 speed.  It is a lot of fun to drive. Can pull pop up trailer with no problem. I was afraid that the 4.2 would not be able to handle the things I do, but was I ever wrong.  The STX is the sport truck version. I mostly got this truck because of the price. At $14,350 it was less than a lot of used trucks.
