New truck.. New towing experience

I posted this on a couple of FORD forums..  thought you guys might have a thought or two as well:

I bought a new 2013 FORD F150 STX super cab, 2wd, (5.0L, V8 with 3.31 electronic locking RR axle) a few weeks ago. I love the truck and always wanted a FORD full size.. always.  I traded in a 2006 Nissan Frontier.

My Nissan actually did a pretty good job pulling my 23 foot WILDWOOD camper. Camper weighs about 3800 pounds empty.. probably about 4500 loaded (no water).. but I was looking for the added comfort of pulling with the bigger FORD.  The Nissan was rated to pull 6100 pounds.. the FORD: 8100,  The Nissan was 265hp.. FORD: 360hp..  plus going from V6 to V8.  

However.. after doing a little (after purchase) looking..  I kinda wish I had bought a truck with the 3.55 or 3.73 axle.  I don't really understand what the difference is..  but i see that the towing capacity is about 1000 pounds more than the 3.31.

Anyway..  I already have the 3.31..  and I think it will pull my present camper with no problems..  just wondering what, and how much..  you guys are towing with the 3.31 electronic lock rr axle?  I might wanna move up to a bigger travel trailer someday.

thanks for all the help.

So, have you towed with it yet? How did it do? Are YOU happy with it? That's pretty much all that matters is if you are happy.

I don't know how big you are planning to go, but I should think that would tow about anything you would want for yourself other than a big 5'er like Tim's.
