Might the adhesive be a water seal between tack welds?
I would never guess that a public auto show would display 'work horse' truck cutaways. show must be HUGE,
I would think the goop where the flanges meet is an adhesive used primarily to reduce flexing and abrasion between the two halves and eliminate potential creaking sounds, but also additional strength & corrosion resistance. They don't want ice and salt spray doing damage. As for protection specifically against water infiltration, there are holes about the frame. The goop minimizes water getting inside the box, but it will get in other ways.
I am not sure how true it is, but I hear the Chicago auto show is the biggest in the country, exceeding the Detroit auto show.....maybe just in recent years.
