First off, not all pickups can be flat towed. Ford, in it's infinite wisdom, did not allow any of it's automatic trucks, especially it's 4x4 1/2 ton units to be flat towed for all the way up to 2012. In 2012, they finally got smart. They made a change to the shift mechanism and programming to the transfer case so, the '12s and above, in 4x4 configuration, are flat towable.
The GM and Dodge have had flat towable 4x4 automatics for years. A simple following of procedures, all spelled out in the owners manual, takes seconds to do and, you're ready to tow them down the road.
I just set up our 2011 GMC Sierra 1500 4x4 for flat towing. I did the install of the dual base plates and, I also did all the wiring for the lights. Very simple to do. We purchased what's called a "Rampage" lift/carrier for the back of the pickup so we could take along our, 2008 Honda GL 1800 Goldwing which, weighs in at about 900 lbs. So, yep, some trucks can be towed and, can carry your toys. Good luck.
