I am looking at an Expedition XLT for pulling my 2017 Keystone Hideout. I am getting mixed messages from car salesman (surprised?). I was told that the 2021 Expedition XLT will tow 9000. It is a rear whell drive with 4 wheel drive. They said it has a Heavy Duty Tow package. It has 3.5 Ecoboost V6 and a 3.73 Avle Ratio. Some other salesman told me a similar vehicle was rated to tow 6500. Trailer weight is 7720. What is the opinion of people on here for towing capacity?
