I have a 2013 F150 Eco CC 4x4 xlt with tow pkg, brake controller. Not a max tow or max payload. I think mine is rated at 9600 towing cap but you run out of payload long before you get there. Rv dealers will tell you it can tow anything :)
Mine has 48,000 miles, over 12,000 towing. First a 21ft TT weighing in about 5200 lbs loaded. Now a 24' TT weighing in about 6200lbs loaded. It tows the 6200lbs great. Been to florida keys 3 times with it and just made a trip to NC mountains. When you want power it is there. We have a wd hitch and have no problems with sway.
I had a 2004 F150 4.6 v8 before. The Eco pulls way better although the 4.6 is not known for it's power lol. My GF and I wanted a little longer and heavier TT when we traded up in Dec but we are pretty much maxed out payload wise at 6200 loaded. That being said, it pulls the 6200 lbs as well as it did 5200lbs. You will be pleased with the power.
Only problem I have had with the truck is a battery failure under warranty and a couple of recalls, which were not problems but were fixed.
