What does that circle thing do on top of Sentinel Prime's truck mode? It looks like can hook on something but what. Or it is there just because the real fire truck has it, too.

I haven't found a use for it. I assume it's for vehicle accuracy, in which case the question is: what does it do on the truck?

Maybe where a hand held fire hose is supposed to wrap around?

I think it's a game table like in the Millennium Falcon...just didn't get the proper paint apps.

Probably just there because the real truck has one. Not sure what it is but you can see it on photo 8 at this page,

Okay, it is there because the real truck has it (I saw it in the movie as well). When I was in Navy, this type of rod is used everywhere on the ship for wrapping and tightening ropes. Just guess it serves the same purpose on a fire truck. In the toy, I guess I can use it to hang Sentinel in mid air.

One possible anser, since I don't see the pic of the real vehicle with it, is that it's there for Fording, but I don't see why a fire truck would need to ford. Perhaps it's for stowing the hose that is taken up the ladder?

it was put there by aliens to confuse the human race.

It could be a exhaust went for the water pump.
