I thought the front bumper on this was particularly unusual. Purpose built?

I knew a guy that had a similar sized set-up on the back of a Dodge truck. It had valves and a hose, and he’d fill it with air from his compressor so he could air his tires up in the woods. I never saw it used, so I have no idea if it was an effective air tank or not.
