2011-up SuperCrew 4x4 with 3.55 axle, EcoBoost engine and 6.5' bed has a GCWR of 15,500 pounds. Empty truck weighs 6,000 so the tow rating is 9,500 if there is absolutely nothing in the truck but a skinny driver.
So am I OK with hauling my trailer with the regular tow package and the 3.55 axle or do I need to move up?
You will be overloaded with hitch weight of 650 pounds, assuming you have the normal stuff in the truck, such as at least one adult passenger, some tools and a spray-in bedliner. That truck has plenty of GCWR to pull
the weight, but not enough GVWR to haul
the hitch weight unless you have at least the max tow pkg.
My 2012 SuperCrew EcoBoost 4x2 has a GVWR of 7,100 pounds, and when on the road with my TT that has 650 pounds hitch weight, I'm overloaded over the GVWR of my truck. The GVWR on a 4x4 is 100 pounds more, but the 4x4 components weigh more than 100 pounds, so you'll be even more overloaded than I am.
So as a minimum you neeed the Max Tow pkg that will pump up the GVWR to 7,700 pounds.
Does GVWR = Truck weight + passenger weight + hitch weight + cargo weight?
Yes. GVWR is the max weight you can have on the 4 truck tires without being overloaded. Including hitch weight and a full tank of gas. And that's usually the limiter on a truck with single rear wheels. With normal hitch weight of around 12 to 15%, the F-150 EcoBoost can pull
a lot more weight than it can haul
the hitch weight.

No. That's GCWR (gross combined
weight rating). GVWR (gross vehicle
weight rating) is the weight on the 4 truck tires, not including the weight on the trailer tires.
For 2013 F-150s sold in the USA, the trailer tow pkg is std on FX and Lariat and above trim, and optional on lesser trim levels. It includes the receiver, 7-pin wiring harness, upgraded radiator, auxiliary tranny cooler, and selectshift tranny.
The Max Tow pkg is the same as the trailer tow pkg, plus it ads the telescoping tow mirrors, the integrated trailer brake controller (ITBC),and minor changes to the rear bumper and suspension to result in an additional 500 pounds of GVWR.
The HD Payload pkg is almost a different truck. It has 8,200 pounds GVWR, with heavier duty wheels and tires and suspension. Way back when (1997-1999), Ford put F-250 badges on that pkg and called it the F-250 LD (light duty). But that confused the heck out of a lot of folks, so thay dropped the misleading badges and have called it the F-150 HD since the Y2K model year.
Max Tow without HD Payload requires 3.73 axle ratio with E-Locker diff. HD Payload pkg requires 3.73 axle with limited slip rear axle, and with the 3.73 LS axle you get both max tow and HD Payload. If you go to Ford Build&Price, you won't see either the max tow pkg or the HD Payload pkg unless you first choose 3.73 axle. With EcoBoost engine, if you choose 3.73 e-locker, the system will automagically add the max tow pkg. If you choose 3.73 LS, the system will automagically add both the max tow and HD Payload packages.
City dealers don't usually order either max tow or HD Payload pkg for the trucks they have in stock. So if you want your truck fixed up right for towing, then you should count on ordering it and waiting about 6 weeks for it to arrive.That way you get exactly what you want with no compromises.
Note: The above applies to F-150s ordered for sale in the USA. Canadian specs are slightly different. So if you're in Canada, find a copy of the Canadian F-150 order guide to see what is available for your truck.
