From a quick google search, what I am reading is it has an upgrading charging system, and front suspension. I dunno all the specifics, just what google led me to. Here's a post from another forum where the guy supposedly checked with a dealer concerning this package also.

I double-checked with my Ford dealer, and I was right. Of course.
There is no such thing as an ambulance package on a pickup. It has to be either a chassis cab truck or a "cutaway" van chassis. Ford requires all dealers to include the "option" code for "this is not an ambulance" on all trucks that do not have the ambulance pkg.
The diesel engine in a 2009 cutaway van chassis is a 6.0L. The diesel engine in a 2009 chassis cab truck is a 6.4L. You can now even get a 6.0L diesel engine in a 2009 F-350 Super van. So don't believe those that say you cannot get a 2009 diesel-powered Ford van.
The dealer said almost all ambulances are on the cutaway van chassis instead of the chassis cab chassis, because of the walk-through ability in the van.
And yes, the ambulance pkg includes dual altenators. I asked if any of the rules regarding the ambulance pkg have changed in the last few years, and he said no.
One thing puzzles me. Ford said they couldn't make the 6.0L engine comply with 2008 emissions requirements, so they had to come out with a new engine, the 6.4L. But now they backtrack and say the 6.0L is fine in a 2008 or 2009 cutaway van.
(No indication why the 2009 vans have the 6.0L instead of the 6.4L. My guess is the van engine is different because it has no intercooler, so Ford didn't want to develop and get EPA approval of another engine combo. It was easier to add the exhaust system from the 6.4L to the 6.0L than to test the 6.4L with no intercooler.)
