Call it what you like, but when you cannot remove the cab, or firewall/cowl/floor whatever, from the frame because it is welded together it is generally considered unibody. Everything painted white is one huge inseparable piece, just as is the cutaway cab and chassis on a View/Navion, etc. You can see the step well, lower half of the door pillar, RH seat mounting box. Its basically just a cutaway cab they left a bunch of major pieces off of.
In autos there is a spot welded "frame" added to the body, and yes the body carries the load, but that is impossible here. Look under a regular Sprinter van (which is unibody) and you find a very similar looking frame welded to the body.
Here is a 2006 3500 undersides. Basically the same frame rails, sans the upper cap, they welded the lower channel of the ladder frame to the bottom of the van body.
Its all about parts interchangeability, make as much stuff interchange as possible, fewer special parts to make.
