Towing guide says 13,200 only available on a 2018 F-150 XL SuperCrew®,6.5' box, 3.5L EcoBoost engine, 4x2 andMax Trailer Tow Package. Decent work truck but bet not too many built to that spec.
Max payload of 3270 is on a 2018 F-150 XL RegularCab, 8' box, 5.0L engine, 4x2, Heavy-DutyPayload Package and 18" heavy-dutywheels. Also rare.
My truck is a 2018 F-150 Lariat SCREW, 6.5' box, 3.5L EcoBoost engine, 4x4, Heavy-DutyPayload Package and 18" heavy-dutywheels. Payload is 2406 and tow capacity should be 11,500 according to the guide. GCVWR is 17,100 lbs. I ordered this one specifically for towing my toy hauler. Very rare to find a HDPP truck in inventory anywhere. Almost all are special orders.
