When I bought my 2011 DRW, there were 3 ways to get the heavier front springs.
The camper package, snow plow package and the FX4 off road package.
All Ford diesels from 2011 up have an exhaust brake, the 2015 has a better one, along with a new turbo and you have more control over the exhaust brake.
I have dual alternators and would not like to be without them. Depending on your options you may have to get the heavy duty dingle alternator.
If you get the supplemental heat option(worth the money), you will need at least the heavy duty alternator.
At start up(especially on a cold morning) I have a heavy electrical load.
You may have to wait for the glow plug light to go off before starting,which sucks juice, both seat heaters going, headlights, plus the over 30 lights the DRW has,supplemental heat, which is about 1200 watts, you have no control over when it goes on or off.My air compressor for air bags etc., usually starts.
So on start up, I can be drawing over 200 amps easily.There are many other electrical draws that I haven't mentioned.
FX4 is kind of a joke. The most valuable thing in the FX 4 package to my way of thinking is the sticker. You get different cheap shocks, some skid plates and a useless hill descent button on the dash as well as that nice sticker. The Fx4 F350 4x4 diesel crew cab still only gets the 5600 lb front springs, which I believe are heavy enough. Anyway I wouldn't want to sacrifice ride to get heavier front springs.
