Engine coolant flush

Went to do a coolant flush and could only get half of the coolant out using the drain plug on the bottom of the rad. Where else is a drain plug on a 2011 6.2 f250?

well, that is not a flush, that is a drain and fill. Just repeat next year or 2 and you would be good to go...in my book

I always take the thermostat out and blow all the old antifreeze out of the motor with my shop vac.

There is no other drain plug.

With the advent of the new type of coolant used in cars and trucks these days, you need to determine exactly what flushing chemicals are compatible with your particular vehicle. Using the wrong thing can really gum up the works - literally.
If you are wanting to change the coolant because it is time, and there is no indication of a problem or corrosion, a simple drain and fill is probably the best route to go. In this case, like Don123, I would used compressed air to blow the old coolant out. This helps prevent mixing old coolant with new, providing your engine with maximum protection.
If you truly need to flush the heating/cooling system due to excessive corrosion, I strongly recommend using only Ford flushing chemicals. Those chemicals you see at Auto Zone etc. that say they are compatible with all colors of antifreeze really aren't.
