It got everyone else right - densely packed into their alt mode.
For Prime though, maybe the truck was an unexpected mode of transportation for a Cybertronian device such as TeleTraan 1? It mapped out Prime's body to the cab, and was then confused to see that the trailer was naturally kept largely empty. Again, in keeping with the them of blending in, it put as little in there as possible :Roller and a few little doodads. Maybe some of what was there was added to perhaps provide a temp triage unit for wounded, for use by Ratchet and Ironhide, and temporary armoured transportation for soldiers too damaged to move on their own (even though in the cartoon they work around that in different silly ways anyway).
Maybe it was simply a case of it being partially damaged ie not thinking at it's best, trying to stay as true as it could to the earth equivalent vehicles , while still adding in some field units/area for the soldiers/ Prime?
If we want to throw the toys into the mix, you could maybe argue it did it to Ratchet first (the med bay), that worked perfectly, and so it adapted it for Ironhide, and finally the much larger Prime.
