Air bags are needed for a 10500 lb 5ver? I pulled a toy hauler 5ver weighing about 11800 loaded with a 2005 F250 CC, and the rear bumper went down less than an inch. No airbags, but did have Timbrens.
There is a big difference between your 2005 and the OPs 2011 suspension, period.
I have a 2013 F250 and it DOES drop more than our 2006 F250 hauling our same 26ft TT.
I suspect that Ford made a large change to the spring rates AT THE BEGINNING of loading. The result is a bit softer "ride" unloaded and the rear sags a bit more than would be expected under load.
#40fan has it right, Ford had a lot of "complaints" and offered a TSB which swaps the 2" F250 block between the axle and spring for a 4" F350 block. The additional 2" should level out the ride while under load without the need for adding "bags".
I would go that route first before dumping money into a bag system and it MAY NOT COST ANYTHING to get the block swap done.
