The Gross Axle Weight Ratings GAWR differ according which options you have.
I believe the Reg Tow rear GAWR is about 3850#, my Max Tow rear GAWR is 4050# and the HD Payload with its 7 lug axle and wheels is 4800#.
You can find the GAWR on your truck's door jamb.

xcntrk pretty much nailed my understanding of it. I would note that packages do vary by year, and there are features that aren't in a package but you get a different way. My 2013 has Trailer Tow Package plus Trailer Brake Controller, and Trailer Sway Control.

The regular tow package lays all the foundation for towing including; hitch receiver, 4-7 pin wiring, engine & transmission coolers, etc.
The max-tow option extends upon the regular tow package and adds the rear bumper upgrades (additional hitch support), towing mirrors, stiffer rear springs, 3.73 and up gearing w/e-locker, and integrated brake trailer controller. This bumps the GVWR up as well. Both the trailer brake controller and gearing selections can be optionally added on the regular tow package.
Finally the HD tow Payload, not tow option extends upon the above two by adding 7-lug hubs/wheels, even stiffer springs (all the way around) Do not believe this is true re: springs. They have the same part numbers, stiffer shocks, different wheels, and LT tires. There are some configuration nuances with this package between the Eco and 5.0 platforms. On the Eco you require the max-tow in order to select the HD package, whereas on the 5.0 you can build the HD package directly from the regular tow package. This is because there is no Max Tow option avail for the 5.0. The HD payloadpackage maxes out the GVWR and RGAWR

The 2012 F150 Source Book mentions 3 different rear leaf spring packs, but doesn't say which are used with the different options.
They are:
Total Thickness at Pad --- Rating at Ground
1.623" --- 3500#
1.67" --- 3700#
1.86" --- 3850#
It also lists 10 different front coil springs, each with a different "wire" diameter, but only mentions 2 as being specifically for the HD Payload package (and 2 for the Raptor). There's no mention of MaxTow.
Presumably you could measure the "wire"diameter of your front coils and the rear leaf spring pack thickness to determine which springs are actually on your truck. You would have to make pretty accurate measurements though.
Also, the Source Book shows that the MaxTow steering is different, with a slower Rack Speed in some configurations.
And the SCab and RegCabs only gets the thicker frame with the HD Payload option, whereas it's standard with the SCrew (but just the long-wheelbase version).

Any dealer will be able to pull up the build sheet simply by providing the VIN number, and provide the info. If they tell you other, they are just too lazy to help.

Page-99:
HD payload option has different front-coils with thicker coil wire and increased deflection rate, and HD has different rear main leaf to include an additional leaf altogether (above and beyond the other RGAWR ratings)
And from the 2013 towing specifications:

Page-2:
The HD payload option is available on a "5.0L 4-Valve V8" platform with a GCWR of 15,300 and axle ratio of 3.73.
Page-4:
F-150 Heavy-Duty Payload Package (Option Code 627)
