Ford Repair: Ford expedition towing, 2005 ford expedition eddie bauer, 2005 ford expedition

Question
Hi, I have a 2005 ford expedition eddie bauer 2wd.  I am wanting to tow a camper with this suv but I am unsure about the towing limits.  The book says it can haul 6000lbs but if you have the towing package it can tow 8900lbs.  What does the  heavy duty towing package have that I don't have?  I would like to tow approx 7500lbs.  I hope you can help.
                  Thank you very much,

Answer
Ronald-

  To be honest, trucks were never my specialty, so I'm not entire certain.  I would imagine it has a stronger hitch and mounting points, better frame bracing, and probably and a higher final drive ratio.  There may even be minor transmission differences since towing puts more strain on a transmission.  Hope this helps.
