I think what you're asking is if the Reese Puck Mount Adapter will fit your truck and hitch?
If the Reese adapter you're looking at is the same as I have it will fit the Ford "Underbed fifth wheel" factory option.
Here is the link for what I ordered to fit my 2013 F250:

Essentially, it adapts the "in bed pucks" to any hitch that fits the "bed rails". I use it with a Curt 16K hitch. It will mount with any hitch that uses "in bed rails"...
It's about twice the price I bought mine for on Amazon last June, so you may find it cheaper somewhere else, but the Reese 30156 Adapter is what you need to get.
Hope this helps, any questions, just ask, I've been pulling with this adapter for about a year now.
