You'll be fine. The 4.6 isn't exactly a powerhouse, but It'll get you there. Having a 2WD is in your favor, as it weighs less. To those who mentioned the 6 speed; if he has a 4.6, he has a 4 speed. As for loading the TT, you don't have to pull it completely empty. Just don't over do it, and put only enough water in to use the bathroom on the road a couple times and you'll be fine. I'd load it up for camping, and do a test tow around home and see what you think. Most importantly is a good hitch set up. I towed my current trailer (7600 lbs GVWR), with a 2003 F150, 5.4, 3:55's with an equal-I-zer hitch and it did fine. Good luck.
