We were talking about a 2011 F-150, not the 2010.
Numbers are different.
Load capability and Towing Capability are two different bears.
Load capability is what your F-150 can CARRY without overloading the frame or axles.
Towing capability is what your engine, trans, and rear can PULL, (not necessarily STOP).
Gross combined weight is the maximum your two components (truck and camper) can weigh without an unsafe condition occurring. Can't stop, Frame, Engine, Trans, or rear damage.
I used the specs from the attached pdf file.
Truck 4x4 - the 4x2 is slightly different.
GCWR = 15,400
Max Towing = 9700 camper
Max Gross Weight of the TRUCK = 8200 pounds
Payload with a 4x4 = 1491 pounds
So, the curb weight of your truck (empty with a tank of gas and you - No hitch no family - no junk) is 8200 (GVWR)-1491(max payload) = 6709 pounds.
Obviously you can not max out the truck and max out the camper since the max the truck can weigh is 8200 plus 9700 camper = 17,900 pounds, so something has to give to remain under the 15,400 pounds the two can weigh together.
If you max load the truck at 8200 pounds, the biggest camper you can tow is 15,400 pounds minus the 8200 of the truck = 7,200 pound max loaded camper (NOT DRY WEIGHT - Full up loaded) The 1491 payload is all the stuff carried by the truck INCLUDING the tongue weight transferred by the weigh distributing hitch (required for the max tow rating) Typically 15% and a minimum of 10% of camper weight. Loading will be critical for you to avoid severe sway at 10% tongue weight.
Dry weight means nothing here. You need to know the GVWR of the Camper. That is the Unloaded Weight (off the yellow sticker on the camper) plus all your gear (max payload). Lets say that that number is 8200 pounds. 7000 UVW plus 1200 pounds payload.
15% of 8200 pounds = 1230 pounds of tongue weight ON the truck.
Add 100 pounds of WD hitch and your Family must not weight more than 160 pounds or you will over gross your truck.
